Bare Die Product Detail: LM317L

Regulator output <= 300mA:
The LM317L high reliability 0.1A positive voltage regulator is equipped with internal limiting + thermal shutdown features for overload immunity. The die is optimised for small size & ease of use. Output voltage is set by x2 external resistors.

With the smallest bare die footprint in the industry by specification, this device is suited for hybrid & MCM designers who need high reliability, adjustable voltage and lower power. Directly replaces the National (TI) LM317L MDC or LM317L MDA.

Features:
** END OF LIFE ** NOT RECOMMENDED FOR NEW DESIGN

Capable of operation at 125°C
Output Adjustable Between 1.2V and 37V
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting
Output Transistor Safe-Area Compensation
Floating Operation for High Voltage Applications
For higher 1.5A output current see LM117
Long term availability with no mask changes
