LOW NOISE 150mA LDO REGULATOR
The RP103x 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 RP103x 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 DFN(PLP)1010-4,
SOT23-5, SC82-AB, SC-88A, therefore high density mounting of the ICs on boards is possible. |
