3 Description

The TLV700 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 most

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 TLV700 series of LDOs are available in 1.5-mm

× 1.5-mm SON-6, SOT-5, and SC70 packages.
