3 Description

The TLV717P series of low-dropout (LDO) linear

regulators are low quiescent current LDOs with

excellent line and load transient performance and are

designed for power-sensitive applications. These

devices provide a typical accuracy of 0.5%.

The TLV717P series offer current foldback that

throttles down the output current with a decrease in

load resistance. The typical value at which current

foldback initiates is 350 mA; the typical value of the

output short current limit value is 40 mA.

Furthermore, these devices are stable with an

effective output capacitance of only 0.1 μF. This

feature enables the use of cost-effective capacitors

that have higher bias voltages and temperature

derating. The devices regulate to specified accuracy

with no output load.

The TLV717P series is available in a 1-mm × 1-mm

DQN package that makes them ideal for hand-held

applications. The TLV717P provides an active

pulldown circuit to quickly discharge output loads.
