Description
The L78M series of three-terminal positive regulators is available in TO-220,
TO-220FP, DPAK and IPAK packages and with several fixed output voltages, making
it useful in a wide range of applications. These regulators can provide local on-card
regulation, eliminating the distribution problems associated with single point
regulation. Each type employs internal current limiting, thermal shutdown and safe
area protection, resulting it essentially indestructible. If adequate heat sinking is
provided, they can deliver over 0.5 A output current. Although designed primarily as
fixed voltage regulators, these devices can be used with external components to
obtain adjustable voltage and currents.
