Recommended alternative parts

  • TPS7A33  -  TPS7A33 is a 1-A negative LDO regulator with very low noise (16 μVRMS)
  • TPS7A39  -  TPS7A39 is a dula pitive-negative 0.15-A LDO regulator with wide input (+/- 30V)

Description

The LM237 and LM337 are adjustable 3-terminal negative-voltage regulators capable of supplying in excess of –1.5 A over an output voltage range of –1.2 V to –37 V. They require only two external resistors to set the output voltage and one output capacitor for frequency compensation.

Features

  • Output Voltage Range Adjustable
    From –1.2 V to –37 V
  • Output Current Capability of 1.5 A Max
  • Input Regulation Typically 0.01% Per Input-
    Voltage Change
  • Output Regulation Typically 0.3%
  • Peak Output Current Constant Over Temperature
    Range of Regulator
  • Ripple Rejection Typically 77 dB
  • Direct Replacement for Industry-Standard LM237
    and LM337
