TO-252 Plastic-Encapsulate Regulators
CJ78D05
Three-terminal positive voltage regulator
DESCRIIPTION
The three-terminal positive regulator employs internal current
limiting, thermal shut-down and safe area protection, making it
essentially indestructible. The device can be used with external
components to obtain adjustable voltage and currents.
