Description
Low Dropout Positive Voltage Regulator
Manufacturer
International Rectifier Corp.
Datasheet
Low Dropout Positive Voltage Regulator
Description
This series of +3.3V voltage regulators are high current,
high accuracy, low dropout regulators and are well
suited for systems where low dropout voltages are
critical. These devices feature protection against
overtemperature, overcurrent, reverse polarity
conditions and voltage spikes. The TO-257AA (Isolated
Tab) hermetic package meets the demand for military/
defense environments.
