Description

This is NEGATIVE VOLTAGE REGULATORS THREE-TERMINAL ADJUSTABLE. LM137, LM237 LM337 THREE-TERMINAL ADJUSTABLE NEGATIVE VOLTAGE REGULATORS . . . . . . . . . OUTPUT VOLTAGE ADJUSTABLE DOWN TO Vref 1.5A GUARANTEED OUTPUT CURRENT 0.3%, V TYPICAL LOAD REGULATION 0.01%, V TYPICAL LINE REGULATION CURRENT LIMIT CONSTANT WITH TEMPERATURE RIPPLE REJECTION : 77dB STANDARD 3-LEAD TRANSISTOR PACKAGES EXCELLENT THERMAL REGULATION: 0.002%, V 50ppm, °C TEMPERATURE COEFFICIENT TO-3 DESCRIPTION The LM137 series are adjustable 3-terminal negative voltage regulators capable of supplying in excess - 1.5A over a -1.2 to - 37V output voltage range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. Also, LM137 regulators are supplied in standard transistor packages which are easily mounted and handled. In addition to higher performance than fixed regulators, the LM137 series offer full overload protection available only in integrated ci.
