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%.

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.

The TLV743P provides an active pulldown circuit to

quickly discharge output loads when the device is

disabled.

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

and DQN (X2SON) packages.
