What the CJ78L05 family does
The CJ78L05 is a three-terminal positive voltage regulator housed in an SOT-89-3L package. It provides a fixed 5V output with a maximum continuous output current of 0.1A and a total dissipation of 0.6W at 25°C. Key electrical characteristics include a dropout voltage of 1.7V, quiescent current of 6mA, and ripple rejection of 41dB. This component is typically used in applications requiring a stable 5V supply from higher input voltages. It operates across an operating junction temperature range of -40°C to +125°C and supports input voltages up to 30V.
