LM337LM/NOPB

The LM337LM/NOPB is an adjustable 3-terminal Negative Voltage Regulator capable of supplying 100mA over a 1.2 to 37V output range. It is exceptionally easy to use and requires only two external resistors to set the output voltage. In addition to higher performance than fixed regulator, the device 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. Normally, only a single 1μF solid tantalum output capacitor is needed unless the device is situated more than 6-inch from the input filter capacitors, in which case 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 regulator.
