3 Description

The TLV741P low-dropout (LDO) linear regulator is a

low quiescent current LDO with excellent line and

load transient performance and is designed for

power-sensitive applications. This device provides a

typical accuracy of 1%.

The TLV741P device is designed to be stable with a

small, 1-µF output capacitor.

The TLV741P device provides inrush current control

during device power up and enabling. The TLV741P

device 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.

The TLV741P is available in a standard DBV (SOT-

23) package. The TLV741P provides an active

pulldown circuit to quickly discharge output loads.
