DESCRIPTION
The CAT6219 is a 500mA 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 CAT6219 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 2.15V typical.
The CAT6219 offers 1% initial accuracy and low
dropout voltage, 300mV typical at 500mA. Stable
operation is provided with a small value ceramic
capacitor, reducing required board space and compo-
nent cost.
Other features include current limit and thermal
protection.
The LDO is available in fixed and adjustable output in
the low profile (1mm max height) 5-lead TSOT23 and in
the 6-pad 2mm x 2mm TDFN packages.
