3-Terminal Adjustable Output Positive Voltage Regulators

Pin Arrangement

Description

The LM317 is an adjustable 3-terminal positive voltage

regulator capable of supplying in excess of 1.5A over an

output voltage range of 1.2V to 37V. This voltage regulator

is exceptionally easy to use and requires only two external

resistors to set the output voltage. Further, it employs internal

current limiting, thermal shutdown and safe area compen-

sation, making it essentially blow-out proof.

• Output transistor safe-area compensation

• Floating operation for high voltage applications

• Eliminates stocking many fixed voltages

Notes:

Cin is required if regulator is located an appreciable distance from power

supply filter.

Mechanical Data

Case: TO-220 and TO-263 packages

Co is not needed for stability, however, it does improve transient response.

V_out= 1.25V (1 + R₂/R₁) + I_AdjR2

Weight: approx. 1.35g

Since I_Adjis controlled to less than 100µA, the error associated with this

term is negligible in most applications

Case outlines are on the back page.
