DESCRIPTION

The L78M00AB series of three-terminal positive

regulators is available in TO-220 and DPAK

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

shut-down and safe area protection, making it

essentially indestructible. If adequate heat sinking

is provided, they can deliver over 0.5A output

current. Although designed primarily as fixed

TO-220

DPAK

voltage regulators, these devices can be used

with external components to obtain adjustable

voltage and currents.
