* SOP–8 is an internally modified SO–8 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–8 conforms to all external di-

MOTOROLA ANALOG IC DEVICE DATA
The LM317L is an adjustable 3–terminal 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–out 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.
Output Current in Excess of 100 mA
Output Adjustable Between 1.2 V and 37 V
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting
Output Transistor Safe–Area Compensation
Floating Operation for High Voltage Applications
Standard 3–Lead Transistor Package
Eliminates Stocking Many Fixed Voltages
Simplified Application
* Cin is required if regulator is located an appreciable
**
distance from power supply filter.
** CO is not needed for stability, however,
**
it does improve transient response.
Since IAdj is controlled to less than 100
μ
A, the error
associated with this term is negligible in most applications.
