TS39103

1A Ultra Low Dropout Voltage Regulator

with Multi-Function

1/8

Version: A08

TO-252-5L

(PPAK)

General Description

The TS39103 are 1A ultra low dropout linear voltage regulators that provide low voltage, high current output from an

extremely small package. These regulators offers extremely low dropout (typically 400mV at 1A) and very low

ground current (typically 12mA at 1A).

The TS39103 are fully protected against over current faults, reversed input polarity, reversed lead insertion, over

temperature operation, positive and negative transient voltage spikes, logic level enable control and error flag which

signals whenever the output falls out of regulation.
