The LM78L05MK/TR with SOT-89 Linear Voltage Regulator (LDO) manufactured by HGSEMI is a three-terminal, low-dropout voltage regulator that can supply a maximum output voltage of 5V and is capable of delivering up to 100mA of output current. It is RoHS compliant and has an operating temperature range of -40°C to +125°C. It features low-noise, low-ripple current regulation, over-temperature protection, and low quiescent current drain. The maximum input voltage for this device is 18V, making it ideal for low-power applications. It also features short-circuit protection to safeguard against excessive current draw. This device is suitable for battery-powered systems, DC/DC converters, power supply for portable equipment, and other applications where low power dissipation is desired.
