DESCRIPTION

The TLV712xx series of low-dropout linear regulators

(LDOs) are low quiescent current devices with

excellent line and load transient performance. These

devices provide sub-bandgap output voltages; that is,

output voltages less than 1.2 V all the way down to

0.7 V. Therefore, these LDOs can be used to power

processors with operating voltages less than 1.2 V.

These LDOs are designed for power-sensitive

applications. A precision bandgap and error amplifier

provides overall 2% accuracy. Low output noise, very

high power-supply rejection ratio (PSRR), and

low-dropout voltage make this series of devices ideal

for a wide selection of battery-operated handheld

equipment. All device versions have thermal

shutdown and current limit for safety.

Furthermore, these devices are stable with an

effective output capacitance of only 0.1 mF. 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 TLV712xxP series also provides an active pull-down circuit to quickly discharge the outputs.

The TLV712xx series of LDO linear regulators are

available in SOT23-5 and 1,5-mm x 1,5-mm SON-6

packages.
