LM337L

3-Terminal Adjustable Regulator

a fixed resistor between the adjustment and output, the

LM337L can be used as a precision current regulator. Sup-

plies with electronic shutdown can be achieved by clamping

the adjustment terminal to ground which programs the out-

put to 1.2V where most loads draw little current.

General Description

The LM337L is an adjustable 3-terminal negative voltage

regulator capable of supplying 100mA over a 1.2V to 37V

output range. It is exceptionally easy to use and requires

only two external resistors to set the output voltage. Further-

more, both line and load regulation are better than standard

fixed regulators. Also, the LM337L is packaged in a standard

TO-92 transistor package which is easy to use.

The LM337L is available in a standard TO-92 transistor

package, SO-8 surface mount package, and in our new 12

mil diameter bump micro SMD package. The LM337L is

rated for operation over a −25˚C to +125˚C range.

In addition to higher performance than fixed regulators, the

LM337L offers full overload protection. Included on the chip

are current limit, thermal overload protection and safe area

protection. All overload protection circuitry remains fully func-

tional even if the adjustment terminal is disconnected.

For applications requiring greater output current in excess of

0.5A and 1.5A, see LM137 series data sheets. For the

positive complement, see series LM117 and LM317L data

sheets.

Normally, only a single 1µF solid tantalum output capacitor is

needed unless the device is situated more than 6 inches

from the input filter capacitors, in which case an input bypass

is needed. A larger output capacitor can be added to improve

transient response. The adjustment terminal can be by-

passed to achieve very high ripple rejection ratios which are

difficult to achieve with standard 3-terminal regulators.

Features

n Adjustable output down to 1.2V

n Guaranteed 100mA output current

n Line regulation typically 0.01%/V

n Load regulation typically 0.1%

n Current limit constant with temperature

n Eliminates the need to stock many voltages

n Standard 3-lead transistor package

n 80 dB ripple rejection

Besides replacing fixed regulators, the LM337L is useful in a

wide variety of other applications. Since the regulator is

“floating” and sees only the input-to-output differential volt-

age, supplies of several hundred volts can be regulated as

long as the maximum input-to-output differential is not ex-

ceeded.

n Output is short circuit protected

n Available in the 6-Bump micro SMD package

n See AN-1112 for micro SMD considerations

Also, it makes an especially simple adjustable switching

regulator, a programmable output regulator, or by connecting
