OUTLINE
1
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 PLP2020-8 package, 2ch LDO regulators are included in each packages, high density mounting of the ICs
on boards is possible.
