The Texas Instruments REG103GA-A/2K5 is a low-dropout (LDO) linear voltage regulator designed for applications requiring a clean, regulated positive output voltage. It delivers up to 500mA of output current from an input voltage range of 2.7V to 15V. The output voltage is adjustable from 1.3V to 5.5V, with fixed output options of 2.5V, 2.7V, 3V, 3.3V, and 5V available in other variants.
Key electrical characteristics include a typical dropout voltage of 115mV at 500mA load, very low output noise of 33µVrms, and a power supply rejection ratio (PSRR) of 65dB at 120Hz and 20dB at 100kHz. The quiescent current is typically 1mA, dropping to 0.5µA when the device is not enabled. The regulator features enable control, power-good output, foldback current limit, and thermal protection.
The REG103GA-A/2K5 is offered in a surface-mount SOT-223-6 package and operates over a temperature range of -40°C to 85°C. It requires no output capacitor for stability, simplifying design and reducing board space.
