The NJM78M00, 78M12A series of 3-Terminal Positive Voltage Regulators is constructed using the New JRC Planar epitaxial process. These regulators employ internal current-limiting, thermal-shutdown and safe-area compensation making them essentially indestructible. If adequate heat sinking is provided, they can deliver in excess of 500mA output current.
1. Internal Short Circuit Current Limit
2. Internal Thermal Overload Protection
3. Excellent Ripple Rejection
4. Guaranteed 500mA Output Current
