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.
