REG103UA-3.3 General Description

The REG103UA-3.3 is a remarkable low-noise, low-dropout linear regulator that stands out for its superior performance. With a new DMOS topology that delivers a mere 115mV typical dropout voltage at full load, this regulator offers unparalleled efficiency and transient response. Unlike traditional low-dropout regulators, the REG103 doesn't require an output capacitor for stability, saving costs and simplifying design complexities. Its ground pin current is impressively low at only 1mA (at 500mA output) and drops to a mere 0.5µA in standby mode, ensuring optimal power efficiency. The regulator boasts exceptional output noise levels of 33µVrms at 3.3V output, making it an excellent choice for portable communication devices. Precision is a hallmark of the REG103, with on-chip trimming ensuring high output voltage accuracy across varying conditions. With comprehensive protection features such as current limit and thermal protection, the REG103 keeps your electronics safe and reliable
