SBVS401A – JUNE 2020 – REVISED DECEMBER 2020

TLV740P 300-mA, Low-Dropout Regulator

With Foldback Current Limit

1 Features

3 Description

•

Foldback overcurrent protection

Packages:

– 1-mm × 1-mm, 4-pin X2SON

– 5-pin SOT-23

Very low dropout: 460 mV at 300 mA

Accuracy: 1%

The TLV740P low-dropout (LDO) linear regulator is a

low quiescent current LDO with excellent line and load

transient performance designed for power-sensitive

applications. This device provides a typical accuracy

of 1%.

•

The TLV740P also provides inrush current control

during device power up and enabling. The TLV740P

limits the input current to the defined current limit to

avoid large currents from flowing from the input power

source. This functionality is especially important in

battery-operated devices.

Low I_Q: 50 µA

Input voltage range: 1.4 V to 5.5 V

Available in fixed-output voltages:

1 V to 3.3 V

High PSRR: 65 dB at 1 kHz

Active output discharge

•

The TLV740P is available in standard DQN and DBV

packages. The TLV740P also provides an active

pulldown circuit to quickly discharge output loads.
