LM317L
Three-Terminal Adjustable
Output Positive Voltage
Regulator
The LM317L is an adjustable 3鈥搕erminal positive voltage regulator
capable of supplying in excess of 100 mA over an output voltage range of
1.2 V to 37 V. 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
compensation, making them essentially blow鈥搊ut proof.
The LM317L serves a wide variety of applications including local, on card
regulation. This device can also be used to make a programmable output
regulator, or by connecting a fixed resistor between the adjustment and
output, the LM317L can be used as a precision current regulator.

* SOP鈥? is an internally modified SO鈥? pack-
age. Pins 2, 3, 6 and 7 are electrically common
to the die attach flag. This internal lead frame
modification decreases package thermal resis-
tance and increases power dissipation capabili-
ty when appropriately mounted on a printed cir-
cuit board. SOP鈥? conforms to all external di-
mensions of the standard SO鈥? package.

distance from power supply filter.

it does improve transient response.
