IL317L
Typical Applications
IL317L
* 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.
Vout = 1.25 V (1+R2/R1) + IAdjR2
Since IAdj is controlled to less than 100uA, the error associated with this term is negligible in most
applications.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Notes: 1. Imax=100mA, Pmax=625mW (TO-92, SOP-8), Pmax=500mW (SOT-89),
2. Load and line regulation are specified at constant junction temperature. Changes in VO due to
heating effects must be taken into account separately. Pulse testing with low duty cycle is used.
