CAT6221

300 mA CMOS Dual LDO

Regulator

Description

TSOT−23 6−lead package two low dropout regulators (LDO), each

with its own enable pin.

LDO provides fast response time during load current and line voltage

changes.

With zero shut down current and a low quiescent current of 100 mA,

the dual LDO is ideal for battery−operated devices with supply voltage

from 2.3 V to 5.5 V.

voltage, typical 210 mV at 300 mA. Stable operation is provided with

small 1 mF ceramic output capacitors, reducing required board space

and component cost.
