LM217MT STMicroelectronics

LM217M, LM317M Medium current 1.2 to 37 V adjustable voltage regulator Datasheet - production data Description The LM217M and LM317M are monolithic integrated circuits in TO-220 and DPAK packages used as positive adjustable voltage regulators. They are designed to supply until 500 mA of load current with an output voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by one resistive divider only, making the TO-220 DPAK device exceptionally easy to configure and avoiding the use of several fixed regulators. Features Output voltage range: 1.2 to 37 V Output current in excess of 500 mA Line regulation typ. 0.01% Load regulation typ. 0.1% Thermal overload protection Short-circuit protection Output transition safe area compensation Floating operation for high voltage applications Table 1.
