0.3uA超低功耗LDO  ZCC7002

0.3uA Extremely Low Iq, 150mA LDO Regulatorwith Programmable Output Voltage and Enable

一：Description

The ZCC7002 series are low quiescentcurrent and low dropout regulators with 4-level programmable output voltages.These LDOs are suitable for portable battery powered devices.

A precision bandgap and an error amplifierprovide 3% accuracy over line, load and temperature. The extremely life.Furthermore, enable function lowers current consumption when devices aredisabled, and an internal switch discharges output capacitor Cout.

The ZCC7002 series of LDO linear regulatorsalso featuies current limiting and shore-circuit protection for safety.
