RP102K181B-TR - Brand New RICOH IC Chips
-
Description
The RP102K181B-TR is a CMOS-based voltage regulator IC, categorized under IC Chips, which is a component that regulates the power supply voltage of electronic devices. It is designed with high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. With its voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit, and a chip enable circuit, it offers excellent line transient response and load transient response, making it suitable for power supplies for portable communication equipment and battery-powered devices. The ICs come in various packages: SOT-23-5, DFN(PLP)1820-6, and WLCSP-4-P2, making high-density mounting of the ICs on boards possible.
