General Description
The TS39101/2/4 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 TS39101/2/4 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.
On the TS39101/2/4, the enable pin may be tied to Vin if it is not required for enable control.
