LM 317 Power supply
The output is adjustable between 1.25 and 13.5
Volts with a maximum current limit of 1.5 Amps.
The LM317K regulator is internally protected from
current and thermal overloads.
A heat sink will be required for most applications
however.

LM 317 Power supply
The diodes D2 and D3 in the circuit prevent damage to
the regulator during certain adverse conditions such as
the output voltage being higher than the input voltage
to the regulator or the capacitor across R2 from
discharging through the adjustment terminal of the
regulator.

LM 317 IC calculator
LM 317 Voltage Regulator calculator
This Voltage Regulator Calculator will work for most
voltage regulators with a reference voltage (VREF)
of 1.25.
For the LM338 and LM350 regulators, 120 ohms is
typically used for R1.
However, other values such as 150 or 220 ohms can
also be used for R1.www.ustudy.in

LM 317 Current Regulator calculator
This Current Regulator Calculator will work for adjustable
regulators with a reference voltage (VREF) of 1.25.
To determine the output current from the regulator, enter a
value for the program resistor (R1) in ohms and press the
"Calculate" button.
This will calculate the Output Current in Amperes and the
amount of Power Dissipated across R1 in Watts.
