General Description

The TS39100/1/2/3/4/5 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 TS39100/1/2/3/4/5 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 TS39100/1/2/3/4/5, the enable pin may be tied to Vin if it is not required for enable control.
