MC78T00 Series

3.0 A Positive Voltage

Regulators

This family of fixed voltage regulators are monolithic integrated

circuits capable of driving loads in excess of 3.0 A. These

three−terminal regulators employ internal current limiting, thermal

shutdown, and safe−area compensation. Devices are available with

improved specifications, including a 2% output voltage tolerance, on

AC−suffix 5.0 V, 12 V and 15 V device types.

Although designed primarily as a fixed voltage regulator, these

devices can be used with external components to obtain adjustable

voltages and currents. This series of devices can be used with a

series−pass transistor to supply up to 15 A at the nominal output

voltage.

CASE 936

Figure 1. Simplified Application

ꢀA common ground is required between the input and the output voltages. The input voltage

must remain typically 2.2 V above the output voltage even during the low point on the input

ripple voltage.

MC = Specific Device Code

xx = Voltage Option

XX these two digits of the type number indicate voltage.

** C is required if regulator is located an appreciable distance from power supply filter.

** (See Applications Information for details.)

= “A” letter for precise 2% regulators, not

used for standard 4% regulators.

= temperature range, “B” for wide

temperature range, −40°C to +125°C, “C”

for standard temperature range,

0°C to +125°C.

** C is not needed for stability; however, it does improve transient response.
