Description
The RP102K281B-TR is a CMOS-based voltage regulator IC with high output voltage accuracy, extremely low supply current, low ON-resistance, and high ripple rejection. It features a voltage reference unit, an error amplifier, a resistor net for voltage setting, a current limit circuit, and a chip enable circuit. The IC has low dropout voltage and an excellent line and load transient response. It is ideal for power supply for handheld communication devices and comes in SOT-23-5, DFN(PLP)1820-6, and WLCSP-4-P2 packages allowing for high-density mounting.
