Description
The RP101K281D5 is a CMOS-based voltage regulator IC that belongs to the RP101x Series. This IC provides high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. The voltage regulator IC is made up of a resistor-net for voltage setting, a chip enable circuit, an error amplifier, a voltage reference unit, and a current limit circuit. It performs with a low dropout voltage and has a chip enable function. It is designed so that high-density mounting of the ICs on boards is possible.
