Features
Pinout
1. Input (VIN): This pin is where the unregulated input voltage is applied. The input voltage must be at least a few volts higher than the desired output voltage to maintain regulation.
2. Output (VOUT): This pin provides the regulated output voltage. The voltage at this pin is adjustable by varying the resistance between the adjustment pin and ground.
3. Adjustment (ADJ): This pin is used to set the output voltage. By connecting a resistor network between the adjustment pin, ground, and the output pin, users can adjust the voltage from 1.25V up to a maximum of approximately 37V, depending on the input voltage.
The LM317KCS is widely used for applications requiring adjustable voltage regulation, offering outputs in the range of 1.25V to 37V with a typical output current capability of up to 1.5A.
