CAT6221

300 mA CMOS Dual LDO

Regulator

Description

The 300 mA CMOS Dual LDO CAT6221 combines in a single

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

with its own enable pin.

http://onsemi.com

The regulator outputs drive loads up to 300 mA. By design, the dual

LDO provides fast response time during load current and line voltage

changes.

Each LDO is optimized for low noise and high crosstalk isolation.

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.

TSOT−23

TD SUFFIX

CASE 419AF

The dual LDO offers 1% initial accuracy and very low dropout

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.

Other features include fold−back current limit and thermal

protection.

The dual LDO is available in the tiny 6−lead TSOT−23 package

with a maximum height of 0.8 mm.
