OUTLINE
The RP103 Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and load transient response of the RP103 Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are PLP1010-4, SOT23-5, SC82-AB, therefore high density mounting of the ICs on boards is possible.
