LM337规格书详情
描述 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.
特性 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
