The LM317T is a three-terminal, adjustable positive voltage regulator that can supply up to 1.5 amps of current. Voltage Regulator IC LM317 is a popular choice for hobbyists and professionals alike because it is relatively easy to use and can use to create a wide variety of power regulation circuits.
The LM317 Variable Voltage Regulator has an output voltage range of 1.25 to 37 volts, which can set by using two external resistors. The LM317T Adjustable Voltage Regulator also features built-in current limiting and thermal shutdown protection, which makes it safe to use in a variety of applications.
The Variable Voltage RegulatorLM317T also has a minimum input voltage of 3 volts and a maximum input voltage of 37 volts. If the input voltage is below 3 volts, the regulator will not work. If the input voltage is above 37 volts, the regulator will enter thermal shutdown mode to protect itself. The LM317T adjustable voltage regulator has an output voltage range of 1.25 to 37 volts. The output voltage can set by using two external resistors
The LM317T adjustable voltage regulator works by using a feedback loop to maintain a constant output voltage. The feedback loop consists of two resistors, R1 and R2, and the ADJUST pin on the LM317T.
The input voltage is applied to the input pin of the LM317T. The ADJUST pin is connect to the output pin through a voltage divider formed by resistors R1 and R2. The voltage at the ADJUST pin is a fraction of the output voltage.
Features : –
The LM317 Variable Voltage Regulator has an internal reference voltage of 1.25 volts. This reference voltage is compared to the voltage at the ADJUST pin. If the voltage at the ADJUST pin is higher than the reference voltage, the LM317T will increase the output voltage. If the voltage at the ADJUST pin is lower than the reference voltage, the LM317T will decrease the output voltage.
The LM317 Variable Voltage Regulator also has built-in current limiting and thermal shutdown protection. This means that the regulator will not output more current than it is designed to, and it will automatically shut down if it gets too hot. The LM317T adjustable voltage regulator has a number of benefits, including:
Wide output voltage range
Built-in current limiting
Thermal shutdown protection
Relatively low cost
Easy to use
