Elektronische Bauelemente
SM1117A
1A Low Dropout Positive
Adjustable or Fixed-Mode Regulator
RoHS Compliant Product
A suffix of “-C” specifies halogen free
DESCRIPTION
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.
FEATURES
 1.4Vmaximum dropout full load current
 Fast transient response
 Output current limiting
 Built-in thermal shutdown
 Good noise rejection
 3-Terminal Adjustable or Fixed 1.5V, 1.8V,
2.5V, 3.3V, 5.0V
