R1100D221C-TR-F - Brand New RICOH IC Chips
-
Description
This is an R1100D Series, CMOS-based voltage regulator IC with high accuracy output voltage and ultra-low supply current. It consists of a driver transistor, a voltage reference unit, an error amplifier, resistors for setting output voltage, and a current limit circuit. The package for this IC is SON1408-3, which allows for high-density mounting on boards. Its output voltage is fixed with high accuracy, and even if VOUT is shorted to the GND, the included current limit circuit protects the IC from destruction.
