PL78M05XA3 Datasheet | Cystech Electonics

Description .. These regulators employ internal current-limiting and thermal-shutdown, making them essentially indestructible. They can deliver up to 500m A output current, if the case temperature can be kept at Tc=25°C. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The PL78M05XA3 used as a Zener diode/resistor bination replacement, offers an effective output impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower noise.
