3-Terminal Fixed Voltage Positive Regulators

hese voltage regulators are monolithic integrated

With adequate heatsinking they can deliver output

currents up to 1 ampere.

T_{circuits designed as 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

Although designed primarily as a fixed voltage

regulator, these devices can be used with external

components to obtain adjustable voltages and currents.

CIRCUIT SCHEMATIC

Representative Schematic Diagram

Standard Application

TYPICAL CONNECTING CIRCUIT

A common ground is required between the input and

the output voltages. The input voltage must remain

typically 2.0V above the output voltage even during

the low point on the Input ripple voltage.

XX = these two digits of the type number indicate

voltage.

* = Cin is required if regulator is located an

appreciable distance from power supply filter.

** = Co is not needed for stability; however, it does

improve transient response.
