FAST-TRANSIENT-RESPONSE 500mA LOW-DROPOUT VOLTAGE REGULATORS  
FEATURES  
DESCRIPTION  
Open Drain Power-On Reset with 200ms Delay  
(TPS775xx)  
The TPS775xx and TPS776xx devices are designed  
to have a fast transient response and be stable with  
a
10μF low ESR capacitor. This combination  
Open Drain Power Good (TPS776xx)  
500mA Low-Dropout Voltage Regulator  
provides high performance at a reasonable cost.  
Because the PMOS device behaves as a low-value  
resistor, the dropout voltage is very low (typically  
169mV at an output current of 500mA for the  
TPS77x33) and is directly proportional to the output  
current. Additionally, since the PMOS pass element  
is a voltage-driven device, the quiescent current is  
very low and independent of output loading (typically  
85μA over the full range of output current, 0mA to  
Available in Fixed Output and Adjustable  
Versions  
Dropout Voltage to 169mV (Typ) at 500mA  
(TPS77x33)  
Ultralow 85μA Typical Quiescent Current  
Fast Transient Response  
2% Tolerance Over Specified Conditions for  
Fixed-Output Versions  
500mA). These two key specifications yield  
a
significant improvement in operating life for  
battery-powered systems. This LDO family also  
features a sleep mode; applying a TTL high signal to  
EN (enable) shuts down the regulator, reducing the  
quiescent current to 1μA at TJ = +25°C.  
8-Pin SOIC and 20-Pin TSSOP PowerPAD™  
(PWP) Packages  
Thermal Shutdown Protection  
The RESET output of the TPS775xx initiates a reset  
in microcomputer and microprocessor systems in the  
event of an undervoltage condition. An internal  
comparator in the TPS775xx monitors the output  
voltage of the regulator to detect an undervoltage  
condition on the regulated output voltage.  
APPLICATIONS  
FPGA Power  
DSP Core and I/O Voltages  
Typical Application Circuit  
(Fixed Voltage Options)  
Power good (PG) of the TPS776xx is an active high  
output, which can be used to implement a power-on  
reset or a low-battery indicator.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with  
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be  
more susceptible to damage because very small parametric changes could cause the device not to meet its published  
specifications.

TPS775xx, TPS776xx  
www.ti.com  
SLVS232ISEPTEMBER 1999REVISED AUGUST 2007  
APPLICATION INFORMATION  
The TPS775xx and TPS776xx feature very low quiescent current, which remains virtually constant even with  
varying loads. Conventional LDO regulators use a pnp pass element, the base current of which is directly  
proportional to the load current through the regulator (IB = IC/β). The TPS775xx and TPS776xx use a PMOS  
transistor to pass current; because the gate of the PMOS is voltage driven, operating current is low and  
invariable over the full load range.  
Another pitfall associated with the pnp-pass element is its tendency to saturate when the device goes into  
dropout. The resulting drop in β forces an increase in IB to maintain the load. During power up, this IB increase  
translates to large start-up currents. Systems with limited supply current may fail to start up. In battery-powered  
systems, it means rapid battery discharge when the voltage decays below the minimum required for regulation.  
The TPS775xx and TPS776xx quiescent currents remain low even when the regulator drops out, eliminating  
both problems.  
The TPS775xx and TPS776xx families also feature a shutdown mode that places the output in the  
high-impedance state (essentially equal to the feedback-divider resistance) and reduces quiescent current to  
2μA. If the shutdown feature is not used, EN should be tied to ground.  
Minimum Load Requirements  
The TPS775xx and TPS776xx families are stable at zero load; no minimum load is required for operation.  
FB—Pin Connection (Adjustable Version Only)  
The FB pin is an input pin to sense the output voltage and close the loop for the adjustable option. The output  
voltage is sensed through a resistor divider network to close the loop as it is shown in Figure 25. Normally, this  
connection should be as short as possible; however, the connection can be made near a critical circuit to  
improve performance at that point. Internally, FB connects to a high-impedance wide-bandwidth amplifier and  
noise pickup feeds through to the regulator output. Routing the FB connection to minimize/avoid noise pickup is  
essential.  
External Capacitor Requirements  
An input capacitor is not usually required; however, a ceramic bypass capacitor (0.047μF or larger) improves  
load transient response and noise rejection if the TPS775xx or TPS776xx are located more than a few inches  
from the power supply. A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of  
milliamps) load transients with fast rise times are anticipated.  
Like all low dropout regulators, the TPS775xx and TPS776xx require an output capacitor connected between  
OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 10μF and  
the ESR (equivalent series resistance) must be between 50mand 1.5. Capacitor values 10μF or larger are  
acceptable, provided the ESR is less than 1.5. Solid tantalum electrolytic, aluminum electrolytic, and multilayer  
ceramic capacitors are all suitable, provided they meet the requirements described previously.

APPLICATION INFORMATION (continued)  
Programming the TPS77x01 Adjustable LDO Regulator  
The output voltage of the TPS77x01 adjustable regulator is programmed using an external resistor divider as  
shown in Figure 25. The output voltage is calculated using Equation 1:  
R1  
VOUT = Vref x (1 +  
)
R2  
(1)  
Where:  
Vref = 1.1834V typ (the internal reference voltage)  
Resistors R1 and R2 should be chosen for approximately 10μA divider current. Lower value resistors can be  
used, but offer no inherent advantage and waste more power. Higher values should be avoided as leakage  
currents at FB increase the output voltage error. The recommended design procedure is to choose R2 = 110kΩ  
to set the divider current at approximately 10μA and then calculate R1 using Equation 2:  
VOUT  
R1 = (  
- 1) x R2

Reset Indicator  
The TPS775xx features a RESET output that can be used to monitor the status of the regulator. The internal  
comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal  
regulated value, the RESET output transistor turns on, taking the signal low. The open-drain output requires a  
pullup resistor. If not used, it can be left floating. RESET can be used to drive power-on reset circuitry or as a  
low-battery indicator. RESET does not assert itself when the regulated output voltage falls outside the specified  
2% tolerance, but instead reports an output voltage low relative to its nominal regulated value (refer to Timing  
Diagram for start-up sequence).  
Power-Good Indicator  
The TPS776xx features a power-good (PG) output that can be used to monitor the status of the regulator. The  
internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal  
regulated value, the PG output transistor turns on, taking the signal low. The open-drain output requires a pullup  
resistor. If not used, it can be left floating. PG can be used to drive power-on reset circuitry or used as a  
low-battery indicator.

APPLICATION INFORMATION (continued)  
Regulator Protection  
The TPS775xx and TPS776xx PMOS-pass transistors have a built-in back diode that conducts reverse currents  
when the input voltage drops below the output voltage (for example, during power down). Current is conducted  
from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external  
limiting may be appropriate.  
The TPS775xx and TPS776xx also feature internal current limiting and thermal protection. During normal  
operation, the TPS775xx and TPS776xx limit output current to approximately 1.7A. When current limiting  
engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is  
designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the  
package. If the temperature of the device exceeds +150°C(typ), thermal-protection circuitry shuts it down. Once  
the device has cooled below +130°C(typ), regulator operation resumes.  
Power Dissipation and Junction Temperature  
Specified regulator operation is assured to a junction temperature of +125°C; the maximum junction temperature  
should be restricted to +125°C under normal operating conditions. This restriction limits the power dissipation  
the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits,  
calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than or  
equal to PD(max)  
.
The maximum-power-dissipation limit is determined using the following equation:  
T
J(max) - TA  
PD(max)  
=
R
qJA  
where:  
TJ(max) is the maximum allowable junction temperature  
θJA is the thermal resistance junction-to-ambient for the package, and is calculated as  
R
1
derating factor  
from the dissipation rating tables  
TA is the ambient temperature  
The regulator dissipation is calculated using:  
PD = (VIN - VOUT) x IOUT  
Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the  
thermal protection circuit.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2)  
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements,  
improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.  
Customers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.  
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s  
standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this  
warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily  
performed.  
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and  
applications using TI components. To minimize the risks associated with customer products and applications, customers should  
provide adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask  
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services  
are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such  
products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under  
the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is  
accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an  
unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties  
may be subject to additional restrictions.  
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service  
voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business  
practice. TI is not responsible or liable for any such statements.  
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would  
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement  
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications  
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related  
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any  
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its  
representatives against any damages arising out of the use of TI products in such safety-critical applications.  
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is  
solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in  
connection with such use.  
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products  
are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any  
non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
