TLV743P

SBVS310C –JULY 2017–REVISED JUNE 2019

TLV743P 300-mA, Low-Dropout Regulator

1 Features

3 Description

The TLV743P low-dropout linear regulator (LDO) is

an ultra-small, low quiescent current LDO that

sources 300 mA with good line and load transient

performance. The device provides a typical accuracy

of 1%.

•

Input Voltage Range: 1.4 V to 5.5 V

Stable Operation With 1-µF Ceramic Output

Capacitor

•

Foldback Overcurrent Protection

Packages:

The TLV743P is designed to be stable with a small

output capacitor with a value of 1 µF. The TLV743P

device provides foldback current control during device

power up and enabling. This functionality is especially

important in battery-operated devices.

•

Very Low Dropout: 125 mV at 300 mA (3.3 V_OUT

Accuracy: 1% (Typical), 1.4% (Maximum)

Low I_Q: 34 µA

)

The TLV743P provides an active pulldown circuit to

quickly discharge output loads when the device is

disabled.

Available in Fixed-Output Voltages:

1 V to 3.3 V

The TLV743P is available in standard DBV (SOT-23)

and DQN (X2SON) packages.
