CAT6221

300mA CMOS Dual LDO Regulator

FEATURES

DESCRIPTION

Two outputs with guaranteed 300mA peak

The 300mA CMOS Dual LDO CAT6221 combines in a

single TSOT-23 6-lead package two low dropout

regulators (LDO), each with its own enable pin.

output current

Low dropout voltages of 210mV typical at

300mA

The regulator outputs drive loads up to 300mA. By

design, the dual LDO provides fast response time

during load current and line voltage changes.

Stable with ceramic output capacitors

Independent enable pins

Under voltage lockout

Each LDO is optimized for low noise and high

crosstalk isolation. With zero shut down current and a

low quiescent current of 100μA, the dual LDO is ideal

for battery-operated devices with supply voltage from

2.3V to 5.5V.

No-load ground current of 100μA typical

Full-load ground current of 160μA typical

±1.0% output voltage initial accuracy

±2.0% accuracy over temperature

“Zero” current shutdown mode

The dual LDO offers 1% initial accuracy and very low

dropout voltage, typical 210mV at 300mA. Stable

operation is provided with small 1μF ceramic output

capacitors, reducing required board space and

component cost.

Fold-back current limit and thermal protection

TSOT-23 6-lead, 0.8mm height package

Other features include fold-back current limit and

thermal protection.

APPLICATIONS

Cellular phones

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

package with a maximum height of 0.8mm.

Battery-powered devices

Consumer Electronics
