LOW-DROPOUT, 5 V
REGULATOR — HIGH EFFICIENCY
Especially suited for hand-held, portable, battery-operated equipment such as cellular telephones, the A8181SLB low dropout voltage
regulator provides high efficiency for maximum battery life in a minimum package size.
Equally applicable to camcorders and portable computers, the device provides a fixed 5 V regulated continuous output at almost 200 mA of load current under worst-case conditions.
Under normal operating conditions, output currents over 500 mA are permitted.
A MOSFET pass element delivers high output current with an input-output differential of less than 300 mV.
For high efficiency, the low dropo...
