Ricoh RP109x Series Low Noise LDO Regulator Datasheet
The Ricoh RP109x Series are CMOS-based voltage regulator ICs designed for high output voltage accuracy and extremely low supply current. These regulators feature low ON-resistance, high ripple rejection, and a chip enable function to prolong battery life. They are particularly suitable for power supplies in hand-held communication equipment due to their excellent transient response and ability to operate with small 0.1uF ceramic capacitors.
