The RP150K Series are CMOS-based dual voltage regulator ICs with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. The output voltage of these ICs is internally fixed with high accuracy (1%). The input voltage range is 2.5V to 5.25V.
The Ricoh RP150K Series consists of CMOS-based dual voltage regulator ICs designed for applications requiring high output voltage accuracy and low supply current. These ICs feature a built-in transistor with low ON resistance to achieve low dropout voltage and include a chip enable circuit to prolong battery life in portable systems. The series is suitable for power supplies in hand-held communication equipment, cameras, and other battery-powered devices.
