LM337L 3-Terminal Adjustable Regulator

FEATURES  
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 bypassed  
to achieve very high ripple rejection ratios which are  
difficult to achieve with standard 3-terminal  
regulators.

Line Regulation Typically 0.01%/V  
Load Regulation Typically 0.1%

Eliminates the Need to Stock Many Voltages  
Standard 3-Lead Transistor Package  
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 voltage, supplies of several  
hundred volts can be regulated as long as the  
maximum input-to-output differential is not exceeded.  
Output is Short Circuit Protected  
Available in the 6-Bump DSBGA Package  
See AN-1112 (Literature Number SNVA009) for  
DSBGA Considerations  
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. Supplies with electronic  
shutdown can be achieved by clamping the  
adjustment terminal to ground which programs the  
output to 1.2V where most loads draw little current.  
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. Furthermore, 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 DSBGA  
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 functional  
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.  
Typical Application  
1.2V-25V Adjustable Regulator
