DESCRIPTION

The L78M00 series of three-terminal positive

regulators is available in TO-220, TO-220FP,

SOT-82, SOT-194 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 voltage regulators,

these devices can be used with external

components to obtain adjustable voltages and

currents.
