ULTRA SMALL PACKAGE
VOLTAGE REGULATOR
R1100D SERIES
OUTLINE
NO. EA-117-0506
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 V
OUT
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.
