R1100D SERIES
www.DataSheet4U.com
ULTRA SMALL PACKAGE
VOLTAGE REGULATOR
NO. EA-117-0506
OUTLINE
The R1100D Series are CMOS-based voltage regulator ICs with high accuracy output voltage and ultra-low
supply current developed. Each of these ICs consists of a driver transistor, a voltage reference unit, an error
amplifier, resistors for setting output voltage and a current limit circuit.
The output voltage of these ICs is fixed with high accuracy.
Even if VOUT is shorted to the GND, the included current limit circuit protects the ICs from the destruction.
Since the package for these ICs is SON1408-3, high density mounting of the ICs on boards is possible.
FEATURES
