SM1117A

1A Low Dropout Positive

Adjustable or Fixed-Mode Regulator

Elektronische Bauelemente

RoHS Compliant Product

A suffix of “-C” specifies halogen free

DESCRIPTION

SOT-89

The SM1117A is a low dropout at positive adjustable

or fixed-mode regulator with minimum of 1A output

current capability. The product is specifically designed

to provide well-regulated supply for low voltage IC

applications such as high-speed bus termination and

low current 3.3V logic supply. SM1117A is also well

suited for other applications such as VGA cards.

SM1117A is guaranteed to have lower than 1.4V

dropout at full load current making it ideal to provide

well-regulated outputs of 1.25 to 5.0 with 6.4V to 12V

input supply.
