3 Pin 1.5A Adjustable Negative Voltage Regulator

3 Pin 1.5A Adjustable Negative Voltage Regulator - LM237
Datasheet
 

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
