CJ78M05 Description

Short technical summary and product information.

The CJ78M series, including the CJ78M05, offers reliable positive voltage regulation with multiple fixed output voltages. Designed for applications requiring up to 500mA of output current, these regulators feature internal short-circuit and thermal shutdown protection, making them robust against overload conditions.

 

Key electrical specifications include an output voltage tolerance of ±3% at 25°C, line regulation typically between 3.0-10mV, and load regulation typically between 15-25mV. The dropout voltage is 2.0V at 350mA, and the power supply rejection ratio is 80dB at 120Hz.

 

These regulators operate within a junction temperature range of -40°C to 125°C. They are suitable for various applications such as appliances, building automation, computing, electronic point-of-sale systems, motor drives, portable devices, and telecommunications.

 

The CJ78M05 is available in several package types, including TO-220-3L, TO-251-3L, TO-251S, and TO-252-2L, supporting both through-hole and surface-mount designs.
