The MC78L12ACDR2G is a Linear Voltage Regulator IC manufactured by ON Semiconductor. It is a positive fixed 1 output (1 Amp) 8-SOIC low dropout voltage regulator, which has an output voltage of 12 V. It has a maximum output current of 100 mA and a temperature range of -40°C to +125°C. It also has a quiescent (no load) current of 4 mA. This device requires an input voltage of 6.5V to 18V, making it suitable for a wide variety of applications. It features a protected output, where the output is disabled if the output voltage falls below the UVLO (Under Voltage Lock Out) threshold of 4.3V. The device also features current and thermal limit protection and is ESD protected.
