The Texas Instruments REG103GA-3.3/2K5 is a fixed output low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 3.3V supply. It delivers up to 500mA of output current with a typical dropout voltage of only 115mV at full load, making it suitable for battery-powered and low-voltage systems.
Key electrical characteristics include an input voltage range of 2.7V to 15V, a quiescent current of 1mA in active mode and 0.5µA in shutdown, and a power supply rejection ratio (PSRR) of 65dB at 120Hz and 20dB at 100kHz. The device features a single positive output and is capable of providing fixed output voltages of 2.5V, 2.7V, 3V, 3.3V, or 5V; this specific variant is factory-set to 3.3V.
The REG103GA-3.3/2K5 is housed in a SOT-223-6 package, which is suitable for surface-mount assembly and compact PCB layouts. It is commonly used in power management for portable electronics, embedded systems, and post-regulation stages where space and efficiency are critical.
