RICOH R1100D

ULTRA SMALL PACKAGE
VOLTAGE REGULATOR
R1100D SERIES
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.

OPERATION
these ICs, the output voltage VOUT is detected by Feedback Registers, and the detected output voltage is
compare with a reference voltage by the error amplifier, so that a constant voltage is output.
A current limit circuit against short protection and a chip enable circuit are included.

TYPICAL APPLICATION
In R1100D Series, a constant voltage can be obtained without using capacitors. However, when the wire
connected VIN is long, use a capacitor. Output noise can be reduced with using capacitor.
Insert capacitors with the capacitance of 0.1µF to 2.2µF between input/output pins and GND pin as close as
possible.
