ML7800
SERIES
3-TERMINAL POSITIVE
VOLTAGE REGULATOR
The ML7800 series are 3-Terminal Positive Voltage Regulators. 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 over 1A output current (Please refer to the "thermal design" portion of application note). They are intended as fixed
voltage regulations in a wide range of applications including local (on-card) regulation for elimination of distributution
problems associated with single point regulation. In addition to use as fixed voltage regulators, these devices can be used with
external components to obtain adjustable output voltages and currents.
