TS39100

1A Ultra Low Dropout Voltage Regulator

1/7

Version: C11

SOT-223

TO-252

(DPAK)

General Description

The TS39100 are 1A ultra low dropout linear voltage regulators that provide low voltage, high current output from

an extremely small package. This regulator offers extremely low dropout (typically 400mV at 1A) and very low

ground current (typically 17mA at 1A).

The TS39100 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.
