SG117HVT/883B数据手册Microchip中文资料规格书

描述 Description

The SG117HV and SG117AHV are 3-terminal positive adjustable voltage regulators which offer a higher input voltage range. They are capable of supplying in excess of 0.5A or 1.5A over an output voltage range of 1.25V to 57V, utilizing an input supply voltage up to 60V. A major feature of the SG117AHV is a reference voltage tolerance guaranteed within ± 1%, allowing an overall power supply tolerance to be better than 3% using inexpensive 1% resistors. Line and load regulation performance has been improved as well. Moreover, the SG117AHV reference voltage is guaranteed not to exceed 2% when operating over the full load, line and power dissipation conditions. The SG117AHV adjustable regulators offer an improved solution for all positive voltage regulator requirements with load currents up to 1.5A. In addition to replacing many fixed regulators, the SG117HV/AHV can be used in a variety of other applications due to its ‘floating’ design as long as the input-to-output differential maximum is not exceeded, such as a current source.
