LM340, A

Series

Three-Terminal Positive

Fixed Voltage Regulators

This family of fixed voltage regulators are monolithic integrated circuits

capable of driving loads in excess of 1.0 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 A–suffix 5.0, 12 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

boost output current capability at the nominal output voltage.

A common ground is required between the input and

the output voltages. The input voltage must remain

typically 1.7 V 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. If needed, use a

* 2% regulators are available in 5, 12 and 15 V devices.
