Description
The RP102x Series is a CMOS-based voltage regulator IC that offers high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. It consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit, and a chip enable circuit. The IC performs with low dropout voltage and "chip enable" function. It has excellent line transient response and load transient response, making it suitable for power supply for hand-held communication equipment.
