  • Description

    The RP103K271D-TR is a CMOS-based voltage regulator IC from the RP103 Series. It is designed with high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. This IC 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 its low dropout voltage and chip enable function, the RP103K271D-TR is ideal for power supply applications in handheld communication equipment. It offers excellent line and load transient responses and is available in high-density mounting packages, including PLP1010-4, SOT23-5, and SC82-AB.
