Safe Operation Area (SOA) Curve
These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure. Operation at the
absolute maximum rating for extended periods may reduce device reliability.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions
should be taken when handling and transporting these devices.

Notes: 3. 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.
4.
Test condition for SOT223-3L: TA = 27°C, no air flow, device mounted on 2”X2” polyimide PCB, 2 oz copper,
5.6mmX5.6mm pad.
5.
Test condition for TO252-3L: TA = 27°C, no air flow, device mounted on 2”X2” polyimide PCB, 1 oz copper,
2cmX2cm pad.
6.
Ensures correct operation without entering dropout. Device will continue to operate below this minimum input
voltage under dropout conditions.
