- Output Voltage Range Adjustable
From –1.2Vto–37V - Output Current Capability of 1.5AMax
- 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
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.
