CJ78M08 Description

Short technical summary and product information.

The CJ78M08 is a three-terminal positive voltage linear regulator manufactured by Jiangsu Changjing Electronics Technology Co., Ltd. It offers a fixed output voltage of 8.0V with a tolerance of ±3% at 25°C, and ±5% over the operating junction temperature range of -40°C to 125°C. This regulator can supply an output current of up to 500mA with adequate heat dissipation.

Key electrical characteristics include a typical line regulation of 3.0-10mV and load regulation of 15-25mV at 25°C. The dropout voltage is 2.0V at 350mA, and the power supply rejection ratio is 80dB at 120Hz. The device incorporates internal short-circuit protection, thermal shutdown protection, and built-in current limiting, making it robust against overload conditions.

Available in a TO-252-2L surface-mount package, the CJ78M08 is suitable for applications requiring on-card regulation, such as appliances, building automation, computing, electronic point-of-sale systems, motor drives, portable devices, and telecommunications.

The CJ78M08 is supplied in tape and reel packaging, with a standard package quantity of 2500 units.
