Description
The R1120N281B-TR is a voltage regulator IC in the R1120N series. It is designed with high output voltage accuracy, low supply current, low ON Resistance, and high ripple rejection using CMOS process. The IC consists of a voltage reference unit, an error amplifier, resistors, a current limit circuit, and a chip enable circuit. It features low dropout voltage and a chip enable function. The ICs in the R1120N series are known for their fast dynamic response to line and load, making them suitable for power supply in handheld communication equipment. The output voltage of the R1120N281B-TR is fixed with high accuracy. Its SOT-23-5 (Mini-mold) package allows for high-density mounting on boards.
