The TPS775xx and TPS776xx devices are designed
to have a fast transient response and be stable with
a 10-µF low ESR capacitors. This combination
provides high performance at a reasonable cost.
NC − No internal connection
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 169 mV
at an output current of 500 mA 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 85 µA over the full range of output current, 0 mA to 500 mA). 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 1 µA at T = 25°C.
J
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.
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.
The TPS775xx and TPS776xx are offered in 1.5-V, 1.6-V (TPS77516 only), 1.8-V, 2.5-V, 2.8 V (TPS77628 only),
and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V
for TPS77501 option and 1.2 V to 5.5 V for TPS77601 option). Output voltage tolerance is specified as a
maximum of 2% over line, load, and temperature ranges. The TPS775xx and TPS776xx families are available
in 20 pin TSSOP package.

SGLS012B − MARCH 2003 − REVISED APRIL 2008
APPLICATION INFORMATION
The TPS775xx family includes five fixed-output voltage regulators (1.5 V, 1.6 V, 1.8 V, 2.5 V, and 3.3 V), and
an adjustable regulator, the TPS77501 (adjustable from 1.5 V to 5.5 V).
The TPS776xx family includes five fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V, 2.8 V, and 3.3 V), and
an adjustable regulator, the TPS77601 (adjustable from 1.2 V to 5.5 V).
device operation
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 (I = I /β). The TPS775xx and TPS776xx use a PMOS
B
C
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 I to maintain the load. During power up, this translates
B
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
2 µA. If the shutdown feature is not used, EN should be tied to ground.
minimum load requirements
The TPS775xx and TPS776xx families are stable even 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 26. 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 (0.047 µF 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 10 µF
and the ESR (equivalent series resistance) must be between 50 mΩ and 1.5 Ω. Capacitor values 10 µF or larger
are acceptable, provided the ESR is less than 1.5 Ω. Solid tantalum electrolytic, aluminum electrolytic, and
multilayer ceramic capacitors are all suitable, provided they meet the requirements described previously.

Resistors R1 and R2 should be chosen for approximately 10-µA 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

APPLICATION INFORMATION
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.
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 (e.g., 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 1.7 A. 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.

APPLICATION INFORMATION
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, P
, and the actual dissipation, P , which must be less than
D(max)
D
or equal to P
.
D(max)
The maximum-power-dissipation limit is determined using the following equation:
T max * T
J
A
P
+
D(max)
R
qJA
Where:
T max is the maximum allowable junction temperature.
J
R
is the thermal resistance junction-to-ambient for the package, i.e., 32.6°C/W for the 20-terminal
θJA
PWP with no airflow.
T is the ambient temperature.
A
The regulator dissipation is calculated using:
+ ǒVI * V
Ǔ
P

D
O
O
Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the
thermal protection circuit.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
