RICOH RP153L SERIES 150mA DUAL LDO REGULATOR WITH 2 INPUT PINS handbook

The RP153L Series is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. Each IC 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 have low dropout voltage due to a built-in transistor with low ON resistance, and the chip enable function extends the battery life of each system. The line transient response and load transient response of the RP153L Series are excellent, making them very suitable for power supply in handheld communication equipment. The output voltage of these ICs is internally fixed with high accuracy. The ICs are packaged in DFN1216-8, allowing for high-density mounting on boards. In RP153L, the power supply of each circuit can be individually supplied. The transient response characteristic of the D and E versions has been improved.
