CJ78L09

The CJ78L series is a three terminal positive voltage linear regulator with fixed voltage output. It has a wide input voltage range. The maximum input voltage can reach 30V (or 35V). At the same time, it can also provide 100mA output current under the condition of good heat dissipation. The CJ78L series adopts fixed voltage output without peripheral resistance, which improves the space utilization efficiency of printed circuit board (PCB). In addition, the CJ78L series also integrates internal current limit, short - circuit protection and thermal shutdown, so that it is basically not affected by overload. Therefore, the CJ78L series is widely used in various scenarios, such as card supervision, to eliminate the noise and distribution problems related to single point supervision. When used as a substitute for Zener - diode resistor combination, it can effectively improve the output impedance and reduce the bias current.
