The Texas Instruments REG102NA-3.3/3K is a linear voltage regulator designed for applications requiring a stable 3.3V output at up to 250mA. It operates with an input voltage range of 2.2V to 10V and offers a typical dropout voltage of 150mV at 250mA. The regulator includes an enable pin for power control and features over-current and over-temperature protection.
This device boasts very low noise (28 µVrms) and high PSRR (46dB at 100 KHz), making it suitable for sensitive analog circuits. The output accuracy is within ±2% maximum. The regulator does not require an output capacitor for stability, simplifying circuit design. It is available in small surface-mount packages, including the SOT-23-5.
Applications for the REG102NA-3.3/3K include portable communication devices and battery-powered equipment where efficient and stable power regulation is crucial. Its compact size and low quiescent current (0.4mA typical) contribute to power-sensitive designs.
