LOW NOISE Dual 300mA LDO
The RP150K Series are CMOS-based dual voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting Output Voltage, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip enable function prolongs the battery life of each system. The line transient response and load transient response of the RP150 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 internally fixed with high accuracy (1%). Since the packages for these ICs are DFN(PLP)2020-8 package, 2ch LDO regulators are included in each packages, high density mounting of the ICs on boards is possible.
