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.
