LM317KCS Product Details

LM317KCS Overview


A Tube case is used to deliver this IC regulator. This voltage regulator IC comes in a TO-220-3 case. On the regulater IC chip, there are a total of 3 terminations. Output type Adjustable. As a result of the Linear Voltage Regulator's design, the operating temperature of Through Hole can be adjusted within a specified range. There is a temperature range of 0°C~125°C degrees during operation of the IC regulator. There is a configuration in this voltage regulator IC that specifies that its output function is Positive. A total of 3 pins can be found on the board. In order to deliver prompt, sufficient and reliable performance, this regulator IC has 1 outputs in total. A dropout voltage of 10 volts can be obtained from this voltage regulator IC. There are 3 pins on the chip. As an FYI, this IC voltage regulator has the basic part number LM317. Taking into account the operation requirements, the maximum output current of the IC voltage regulator reaches 1.5A. It operates in the 3.5mA Quiescent Current state. The top supply voltage can be set to 40V volts.
