Description
The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and
D2PAK packages intended for use as positive adjustable voltage regulators.
They are designed to supply more than 1.5 A of load current with an output voltage
adjustable over a 1.2 to 37 V range.
The nominal output voltage is selected by means of a resistive divider, making the
device exceptionally easy to use and eliminating the stocking of many fixed
regulators.
The LM217, LM317 provides an internal reference voltage of 1.25 V between the output and adjustments
terminals. This is used to set a constant current flow across an external resistor divider (see Figure 6. Basic
adjustable regulator), giving an output voltage VO of:
VO = VREF (1 + R2/R1) + IADJ R2
