Description

The TSM114 integrated circuit incorporates all of

the sensing circuitry required to regulate and

protect a multiple-output power supply (3.3V, 5V,

and

±12V) from both over-voltage and

under-voltage.

The TSM114 also includes all of the necessary

functions for housekeeping features, which allow

for safe operation under all conditions, as well as

very high system integration.

A precise voltage reference is also integrated in

the TSM114
