TERMINAL POSITIVE VOLTAGE REGULATORS
TO-220 AB
These voltage regulators are monolithic
integrated circuits designed fixed-voltage regulators
for a wide variety of applications including local, on
card regulation. These regulators employ internal

compensation. With adequate heatsinking they can
deliver output currents in excess of 1.0 ampere.
Although designed primarily as a fixed voltage regulator, these devices can be used with
external components to obtain adjustable voltages and currents.

A common ground is required between the
input and the output voltage. The input voltage
must remain typically 2.0 V above the output volt-
age even during the low point on the input ripple
