DESCRIPTION

The CAT6218 is a 300mA CMOS low dropout

regulator that provides fast response time during load

current and line voltage changes.

The quick-start feature allows the use of an external

bypass capacitor to reduce the overall output noise

without affecting the turn-on time of just 150μs.

With zero shutdown current and low ground current of

55μA typical, the CAT6218 is ideal for battery-

operated devices with supply voltages from 2.3V to

5.5V. An internal under voltage lockout circuit disables

the output at supply voltages under 2.1V typical.

The CAT6218 offers 1% initial accuracy and low

dropout voltage, 180mV typical at 300mA. Stable

operation is provided with a small value ceramic

capacitor, reducing required board space and compo–

nent cost.

Other features include fold-back current current limit

and thermal protection.

The device is available in the low profile (1mm max

height) 5-lead thin SOT23 package.
