Description

The L78MxxAB 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 0.5 A output

current. Although designed primarily as fixed

voltage regulators, these devices can be used

Table 1.
