TERMINAL POSITIVE VOLTAGE REGULATORS


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
current limiting, thermal shutdown, and safe-area
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.
Output Current in Excess of 1.0 Ampere
No External Components Required
Internal Thermal Overload Protection
Internal Short - Circuit Current Limiting
Output Transistor Safe-Area Compensation

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
voltage.
