Introduction
The CJ78L series is a group of three-terminal positive voltage linear regulators with a fixed voltage output. It can support a maximum input voltage of 30V (or 35V) and provide an output current of 100mA with good heat dissipation. The CJ78L series eliminates the need for peripheral resistors to define voltage outputs, which improves the space efficiency of printed circuit boards (PCBs). In addition, the CJ78L series integrates internal current limiting, short-circuit protection, and thermal shutdown, making it virtually unaffected by overload. Therefore, the CJ78L series is widely used in a variety of scenarios, such as card monitoring, to eliminate noise and distribution issues related to single-point monitoring. When used as an alternative to the Zener diode-resistor combination, the CJ78L series can effectively increase the output impedance and reduce the bias current.
