LM337L  
3-Terminal Adjustable Regulator  
Also, it makes an especially simple adjustable switching  
regulator, a programmable output regulator, or by connecting  
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 100 mA 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 and a SO-8 surface mount 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 posi-  
tive complement, see series LM117 and LM317L data  
sheets.  
Normally, only a single 1 µF 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 100 mA 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
