recommended.
The input pin of regulator. Typically a large storage capacitor (0.05Ω
≤
ESR
≤
0.5Ω) is connected from
this pin to ground to ensure that the input voltage does not sag below the minimum dropout voltage
during the load transient response. This pin must always be 1.3V higher than V

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to
absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and
5. ZLDO1117 contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature
exceeded. When activated, typically at 150°C, the regulator Output switches off and then back on as the die cools.

Line Regulation
9. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant
junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.
10. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input
and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.
