3-Terminal Fixed Positive Voltage Regulators

MC78xxCT

TO-220AB

Description

These voltage regulators are monolithic integrated circuits

designed as fixed-voltage regulators for a wide variety of

applications including local, on-card regulation. These

regulators employ internal current limiting, thermal shut-

down, and safe-area compensation. With adequate

heatsinking the MC78xxCT can deliver output currents in

excess of 1.5 ampere.

Pin Definition

1. Input

2. Ground

3. Output

(Heatsink/tab

connected to pin 2)

Although designed primarily as a fixed voltage regulator,

these devices can be used with external components to

obtain adjustable voltages with currents.

Standard Application

Features

• Output current in excess of 1.0 ampere

Input

Output

MC78xx

• No external components required

Cin

0.33µF

0.1µF

• Internal thermal overload protection

• Internal short-circuit current limiting

• Output transistor safe-area compensation

• Output voltage offered in 2% tolerance

Notes:

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.

Mechanical Data

Case: TO-220 Package

xx = these two digits of the part number indicate output voltage.

Cin is required if regulator is located an appreciable distance from power

supply filter.

Case outline is on the back page.

Co is not needed for stability, however, it does improve transient response.
