CAT6220 Datasheet, PDF (1/12 Pages) ON Semiconductor – 300 mA Adjustable Voltage LDO Regulator

CAT6220
300 mA Adjustable Voltage
LDO Regulator
Description
The CAT6220 is a 300 mA CMOS low dropout regulator whose
output voltage is user adjustable that provides fast response time
during load current and line voltage changes.
With 1 mA of shutdown current, an internal no−load operating
current of only 10 mA, and full−load operating current of 40 mA, the
CAT6220 is ideal for battery−operated devices with supply voltages
from 2.3 V to 6.5 V.
The CAT6220 offers 1% initial accuracy and low dropout voltage,
270 mV typical at 300 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 device is available in the low profile (1 mm max height) 5−lead
TSOT−23 and 6−pad 2 mm x 2 mm TDFN packages.
