LM317T Voltage Regulator

Model No: REG-00009

TK. 20.7

Availability: In stock


Category: Regulator

The LM117/LM217/LM317 are monolithic integrated circuit in TO-220, TO-220FP, TO-3 and D2PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V range. The nominal output voltage is selected by means of only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.

  • Operating Temperature Range:0°C to +125°C
  • Maximum Reference Voltage:1.30V
  • Maximum Load Current :10mA
  • Typical Thermal Resistance,Junction-to-Case:4°C/W

Q: Input Voltage koto? Questioned by Shohan33, 11-Oct-2015

Input-output difference should be 3V-40V. Answered by A.R, 13-Oct-2015 10:11 AM

Q: can i use it instead of LM317 IN A VARIABLE POWER SUPPLY? Questioned by xamil69, 11-Mar-2017

Please see the datasheet. The one with 'T' suffix has 1.5A of load current. Please see if that is enough for your power supply. Answered by A.R, 14-Mar-2017 06:22 AM

Q: instead of getting variable voltage as output i am getting almost same output.. that means the output varies about 0.3 volt. would you please help me to make the circuit properly? Questioned by Zalaluddinakbarnayem, 24-Aug-2020
