CAT6218
300 mA CMOS LDO
Regulator
Description
The CAT6218 is a 300 mA 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 150 m s.
With zero shutdown current and low ground current of 55 m A
typical, the CAT6218 is ideal for battery ? operated devices with supply
voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit
disables the output at supply voltages under 2.1 V typical.
The CAT6218 offers 1% initial accuracy and low dropout voltage,
180 mV typical at 300 mA. Stable operation is provided with a small
value ceramic capacitor, reducing required board space and
component cost.
