NCV317 ON Semiconductor, NCV317 Datasheet - Page 2

• Manufacturer Part Number: NCV317
• Description: Positive Voltage Regulator
• Manufacturer: ON Semiconductor

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. T
2. I
3. Load and line regulation are specified at constant junction temperature. Changes in V
4. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die.
5. C
6. Since Long−Term Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average

These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation is the effect of these
temperature gradients on the output voltage and is expressed in percentage of output change per watt of power change in a specified time.
