LM137K/883 Product Details

LM137K/883 Overview


In TO-3 cases, it is packaged. This gadget has 2 terminations on it, each with a different function. Adjustable is the IC Voltage Regulator's output type. There is an output of 1.5A at the moment. 2 pins make up the sum of this IC voltage regulator. As a result of this IC voltage regulator's 1 outputs, it ensures prompt, adequate performance for all your applications. As far as its dropout voltage is concerned, it is 10 volts. The regulator IC has 2 pins. When operating at maximum output current, the regulator IC reaches 1.5A. It operates in the 120μA Quiescent Current state. A system-wide output of -37V volts is possible from this voltage regulator IC. A voltage reference characteristic is specified within a range of -1.275V volts for this regulator.
