STP1117Sxx Series

1.0A Low Dropout Positive

Adjustable or Fixed-Mode Regulator

Elektronische Bauelemente

RoHS Compliant Product

A suffix of “-C” specifies halogen free

DESCRIPTION

SOT-223

The STP1117Sxx series of positive adjustable and

fixed regulators are designed to provide 1A with high

efficiency. All internal circuitry is designed to operate

down to 1.4V input to output differential.

On-chip trimming adjusts the reference voltage to

1%. Current limit the typical value of 1.5A allows to

minimizing the stress on both the regulator and the

power source circuitry under overload conditions.
