RP102Z291B5-TR-F - Brand New RICOH IC Chips
-
Description
The RP102Z291B5-TR-F is a CMOS-based voltage regulator IC with high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. It consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit, and a chip enable circuit. With low dropout voltage and "chip enable" function, it is suitable for the power supply for hand-held communication equipment. The IC comes in SOT-23-5, DFN(PLP)1820-6, and WLCSP-4-P2 packages for high density mounting on boards.
