7 Detailed Description
7.1 Overview
The TLV733P-Q1 belongs to a family of low dropout (LDO) linear regulators. These devices consume low
quiescent current and deliver excellent line and load transient performance. These characteristics, combined
with low noise and good PSRR with low dropout voltage, make this family of devices ideal for portable consumer
applications.
This family of regulators offers foldback current limit, shutdown, and thermal protection. The operating junction
temperature for this family of devices is –40°C to +150°C.

7.3 Feature Description
7.3.1 Undervoltage Lockout (UVLO)
The TLV733P-Q1 family uses an undervoltage lockout (UVLO) circuit that disables the output until the input
voltage is greater than the rising UVLO voltage. This circuit ensures that the device does not exhibit any
unpredictable behavior when the supply voltage is lower than the operational range of the internal circuitry.
During UVLO disable, the output is connected to ground with a 120-Ω pulldown resistor.
7.3.2 Shutdown and Output Enable
The enable pin (EN) is active high. Enable the device by forcing the EN pin to exceed VEN(HI). Turn off the device
by forcing the EN pin to drop below VEN(LO). If shutdown capability is not required, connect EN to IN. There is no
internal pulldown resistor connected to the EN pin.
The TLV733P-Q1 has an internal pulldown MOSFET that connects a 120-Ω resistor to ground when the device
is disabled. The discharge time after disabling depends on the output capacitance (COUT) and the load
resistance (RL) in parallel with the 120-Ω pulldown resistor. The time constant is calculated in 方程式 1:
120 · RL
t =
· COUT
120 + RL
(1)
7.3.3 Internal Foldback Current Limit
The TLV733P-Q1 has an internal foldback current limit that protects the regulator during fault conditions. The
current allowed through the device is reduced when the output voltage falls. When the output is shorted, the
LDO supplies a typical current of 150 mA. The output voltage is not regulated when the device is in current limit.
In this condition, the output voltage is the product of the regulated current and the load resistance. When the
device output is shorted, the PMOS pass transistor dissipates power [(VIN – VOUT) × IOS] until thermal shutdown
is triggered and the device turns off. After the device cools down, the internal thermal shutdown circuit turns the
device back on. If the fault condition continues, the device cycles between current limit and thermal shutdown;
see the Thermal Information table for more details.
The foldback current-limit circuit limits the current allowed through the device to current levels lower than the
minimum current limit at a nominal VOUT current limit (ILIM) during startup. See 图 6-6 to 图 6-8 for typical
foldback current limit values. If the output is loaded by a constant-current load during startup, or if the output
voltage is negative when the device is enabled, then the load current demanded by the load can exceed the
foldback current limit and the device may not rise to the full output voltage. For constant-current loads, disable
the output load until the TLV733P-Q1 has fully risen to the nominal output voltage.
The TLV733P-Q1 PMOS pass element has an intrinsic body diode that conducts current when the voltage at the
OUT pin exceeds the voltage at the IN pin. Do not force the output voltage to exceed the input voltage because
excessively high current can flow through the body diode.
7.3.4 Thermal Shutdown
Thermal shutdown protection disables the output when the junction temperature rises to approximately 160°C.
Disabling the device eliminates the power dissipated by the device, allowing the device to cool. When the
junction temperature cools to approximately 140°C, the output circuitry is again enabled. Depending on power
dissipation, thermal resistance, and ambient temperature, the thermal protection circuit can cycle on and off.
This cycling limits regulator dissipation, protecting the device from damage as a result of overheating.
Activating the thermal shutdown feature usually indicates excessive power dissipation as a result of the product
of the (VIN – VOUT) voltage and the load current. For reliable operation, limit junction temperature to 150°C
(maximum). To estimate the margin of safety in a complete design, increase the ambient temperature until the
thermal protection is triggered; use worst-case loads and signal conditions.
The TLV733P-Q1 internal protection circuitry protects against overload conditions but is not intended to be
activated in normal operation. Continuously running the TLV733P-Q1 into thermal shutdown degrades device
reliability.

7.4 Device Functional Modes
7.4.1 Normal Operation
The device regulates to the nominal output voltage under the following conditions:
• The input voltage has previously exceeded the UVLO rising voltage and has not decreased below the UVLO
falling threshold.
• The input voltage is greater than the nominal output voltage added to the dropout voltage.
• The enable voltage has previously exceeded the enable rising threshold voltage and has not decreased
below the enable falling threshold.
• The output current is less than the current limit.
• The device junction temperature is less than the thermal shutdown temperature.
7.4.2 Dropout Operation
If the input voltage is lower than the nominal output voltage plus the specified dropout voltage, but all other
conditions are met for normal operation, the device operates in dropout mode. In this condition, the output
voltage is the same as the input voltage minus the dropout voltage. The transient performance of the device is
significantly degraded because the pass device is in a triode state and no longer controls the current through the
LDO. Line or load transients in dropout can result in large output voltage deviations.
7.4.3 Disabled
The device is disabled under the following conditions:
• The input voltage is less than the UVLO falling voltage, or has not yet exceeded the UVLO rising threshold.
• The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising
threshold.
• The device junction temperature is greater than the thermal shutdown temperature.
When the device is disabled, the active pulldown resistor discharges the output.

8 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification, and TI
does not warrant its accuracy or completeness. TI’s customers are responsible for determining
suitability of components for their purposes. Customers should validate and test their design
implementation to confirm system functionality.
8.1 Application Information
8.1.1 Input and Output Capacitor Selection
The TLV733P-Q1 uses an advanced internal control loop to obtain stable operation both with and without the
use of input or output capacitors. Dynamic performance is improved with the use of an output capacitor, and can
be improved with an input capacitor. An output capacitance of 0.1 μF or larger generally provides good dynamic
response. Use X5R- and X7R-type ceramic capacitors because these capacitors have minimal variation in value
and equivalent series resistance (ESR) over temperature.
Although an input capacitor is not required for stability, increased output impedance from the input supply can
compromise the performance of the TLV733P-Q1. Good analog design practice is to connect a 0.1-µF to 1-µF
capacitor from IN to GND. This capacitor counteracts reactive input sources and improves transient response,
input ripple, and PSRR. Use an input capacitor if the source impedance is greater than 0.5 Ω. Use a higher-
value capacitor if large, fast rise-time load transients are anticipated, or if the device is located several inches
from the input power source.
图 8-1 shows the transient performance improvements with an external 1-µF capacitor on the output versus no
output capacitor. The data in this figure are taken with an increasing load step from 50 mA to 300 mA, and the
peak output voltage deviation (load transient response) is measured. For low output current slew rates,
(< 0.1 A/µs), the transient performance of the device is similar with or without an output capacitor. When the
current slew rate is increased, the peak voltage deviation is significantly increased. For loads that exhibit fast
current slew rates above 0.1 A/µs, use an output capacitor. For best performance, the maximum recommended
output capacitance is 100 µF.

Some applications benefit from the removal of the output capacitor. In addition to space and cost savings, the
removal of the output capacitor lowers inrush current as a result of eliminating the required current flow into the
output capacitor at startup. In these cases, take care to ensure that the load is tolerant of the additional output
voltage deviations.

8.1.2 Dropout Voltage
The TLV733P-Q1 uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the
dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output
resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with output current because the
PMOS device behaves like a resistor in dropout mode. As with any linear regulator, PSRR and transient
response degrade when (VIN – VOUT) approaches dropout operation.

input and output capacitors are required to achieve the output voltage transient requirements. Capacitance
values of 1 µF are selected to give the maximum output capacitance in a small, low-cost package.

8.2.2.2 Design Considerations
The TLV733P-Q1 can be directly powered off of a battery, as shown in 图 8-4. An input capacitor is not required
for this design because of the direct low impedance connection to the battery.
Eliminating the output capacitor allows for the minimal possible inrush current during startup, ensuring that the
200-mA maximum input current is not exceeded.

Power Supply Recommendations
Connect a low output impedance power supply directly to the IN pin of the TLV733P-Q1. Inductive impedances
between the input supply and the IN pin can create significant voltage excursions at the IN pin during startup or
load transient events. If inductive impedances are unavoidable, use an input capacitor.
