DESCRIPTION

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.

The regulator outputs drive loads up to 300mA. By design, the dual LDO provides fast response time during load current and line voltage changes.

FEATURES

■ Two outputs with guaranteed 300mA peak output current

■ Under voltage lockout

■ 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

■ Fold-back current limit and thermal protection

■ TSOT-23 6-lead, 0.8mm height package

APPLICATIONS

■ Cellular phones

■ Battery-powered devices

■ Consumer Electronics
