LM317KTTRG3 Product Details

LM317KTTRG3 Overview


Deliveries are in Tape & Reel (TR) cases. The package is in a TO-263-4, D2Pak (3 Leads + Tab), TO-263AA case. Basically, the voltage regulator chip is made up of 3 terminations. In this case, Adjustable represents the output type of the Voltage Regulated IC. This part implements 1 regulator ICs, which can be found in the following table. Regulator IC varies the range of Surface Mount operating temperatures. The Voltage Regulated IC operates at a temperature of 0°C~125°C degrees, which is its operating temperature. It is configured for output function Positive on this regulator. The total number of pins in the regulator is 4. This IC regulator has a total of 1 outputs, which ensures a rapid, adequate performance when in use. Several pins on the chip are 3-shaped. As an FYI, this IC voltage regulator has the basic part number LM317. Packing the voltage regulator IC in this way is called TR packing. The maximal output current reaches 1.5A to meet the operating requirements. It operates in the 3.5mA Quiescent Current state.
