AMS317中文资料Voltage Regulator数据手册Advanced Monolithic Systems规格书

描述 Description

series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The AMS317 devices are pin compatible with other three-terminal regulators and are offered in the TO-220, TO-263(plastic DD), TO-252 package (DPAK) and in the low profile surface mount SOT-223 package.
