Description
The R1120N421B-TR is a voltage regulator IC from the R1120N series. It is designed with high output voltage accuracy, low supply current, low ON resistance, and high ripple rejection using CMOS process technology. This IC includes a voltage reference unit, an error amplifier, resistors, a current limit circuit, and a chip enable circuit. With low dropout voltage and a chip enable function, it is ideal for power supply applications in handheld communication equipment. The R1120N421B-TR comes in a SOT-23-5 (Mini-mold) package, allowing for high-density mounting on boards.
