FEATURES

DESCRIPTION

The TLV717xx series of low-dropout (LDO) linear

2

•

Very Low Dropout: 215 mV at 150 mA

regulators are low quiescent current LDOs with

•

Accuracy: 0.5% (typical)

excellent line and load transient performance and are

•

designed for power-sensitive applications. These

devices provide a typical accuracy of 0.5%.

•

Available in Fixed-Output Voltages:

The TLV717xx series offer current foldback that

throttles down the output current with a decrease in

•

High PSRR:

load resistance. The typical value at which current

–

70 dB at 1 kHz

foldback initiates is 350 mA; the typical value of the

–

50 dB at 1 MHz

output short current limit value is 40 mA.

•

Stable with Effective Output Capacitance:

Furthermore, these devices are stable with an

effective output capacitance of only 0.1 µF. This
