500mA CMOS LDO Voltage Regulator

(Preliminary)

SE5218

Note 1: Exceeding the absolute maximum rating may damage the device.

Note 2: The device is not guaranteed to function outside its operating rating.

the regulator will go into thermal shutdown.

See “Thermal Consideration” section for details

Note 4: Output voltage temperature coefficient is the worst case voltage change divided by the total temperature range.

Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing.

Parts are tested

for load regulation in the load range from 10mA to 500mA.

Changes in output voltage due to heating effects are

covered by the thermal regulation specification.

Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its

nominal value measured at 1V differential.
