The LM78L05ACM/TR is a Linear Voltage Regulators (LDO) ROHS manufactured by HGSEMI, and it comes in an 8-pin Small Outline Package (SOP-8) form factor. It is a three-terminal, fixed output voltage regulator with an output voltage of 5V. It offers reverse-sinking capability up to 100mA to ground. It has an input voltage range of 3V to 18V, and a minimum current of 1mA. The maximum junction temperature of 105°C, the operating junction temperature of -40°C to +125°C, and it also has an over temperature protection. It features output current limiting and thermal shutdown for protective parts. It is also designed with Analog Temperature Indicating Output (ATO) while featuring a low dropout voltage and low quiescent current. It is typically used in notebook PC, office automation, audiovisual equipment, and instrumentation applications.
