Description
The R1120N421B is an IC chip belonging to the voltage regulator ICs category. These voltage regulator ICs feature high output voltage accuracy, low supply current, low ON resistance, and high Ripple Rejection by CMOS process. Each of these voltage regulator ICs is made up of a voltage reference unit, an error amplifier, resistors, a current limit circuit, and a chip enable circuit. The package for these ICs is SOT-23-5 (Mini-mold) package which allows for high density mounting of the ICs on boards.
