3 Description

The TLV702 series of low-dropout (LDO) linear

regulators are low quiescent current devices with

excellent line and load transient performance. 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 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 TLV702P series also provides an active pulldown

circuit to quickly discharge the outputs.

The TLV702 series of LDO linear regulators are

available in SOT23-5 and 1.5-mm × 1.5-mm WSON-6

packages.
