Description
The RP100K281D is a CMOS-based voltage regulator IC from the RP100x Series. It features high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. This IC consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit. With low dropout voltage and a chip enable function, it provides excellent line and load transient response, making it suitable for power supply in handheld communication equipment. The RP100K281D is available in SOT-23-5 and PLP1612-4 packages, allowing for high density mounting.
