Description

General part information

LM337-N-MIL Series

The LM337L is an adjustable 3-pin negative voltage regulator capable of supplying 100 mA over a –1.2-V to –37-V output range. The LM337L is easy to use and requires only two external resistors to set the output voltage. Both line and load regulation are better than standard fixed regulators. The LM337L is packaged in a standard, easy-to-use TO-92 transistor package.

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 pin is disconnected.

Normally, only a single 1-µF solid tantalum output capacitor is required unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is required. A larger output capacitor can be added to improve transient response. The adjustment pin can be bypassed to achieve very high ripple rejection ratios, which are difficult to achieve with standard 3-pin regulators.
