CAT6219
500 mA CMOS LDO
Regulator
Description
The CAT6219 is a 500 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 ms.
With zero shutdown current and low ground current of 55 mA
typical, the CAT6219 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 2.15 V typical.
The CAT6219 offers 1% initial accuracy and low dropout voltage,
300 mV typical at 500 mA. Stable operation is provided with a small
value ceramic capacitor, reducing required board space and
component cost.
Other features include current limit and thermal protection.
The LDO is available in fixed and adjustable output in the low
profile (1 mm max height) 5−lead TSOT23, 6−pad 1.5 mm x 1.5 mm
WDFN and in the 6−pad 2 mm x 2 mm TDFN packages.
