The 78L12G-AB3-R is a linear voltage regulator manufactured by Unisonic Technologies. It is a three-pin SOT-89 package with RoHS certification. It is capable of outputting regulated voltages ranging from 1.2V to 15V, with a maximum output current of 800mA. It features on-chip thermal shutdown protection and short-circuit current limiting. It is a low dropout voltage regulator with a typically low quiescent current of only 32µA. The 78L12G-AB3-R also features improved ripple rejection, high power supply rejection ratio, and improved output voltage accuracy. It is suitable for applications where low noise, low power consumption, and high accuracy are needed.
