Note 1:
OUT may be shorted to GND for 1sec without damage, but shorting OUT to V+ may damage the device and should be
avoided. Also, for temperatures above +85°C, OUT must not be shorted to GND or V+, even instantaneously, or device
damage may result.
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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2:
In the test circuit, capacitors C1 and C2 are 150µF, 0.2Ω maximum ESR, aluminum electrolytics.
Capacitors with higher ESR may reduce output voltage and efficiency. See
Capacitor Selection
section.
Note 3:
Specified output resistance is a combination of internal switch resistance and capacitor ESR. See
Capacitor Selection
section.
Note 4:
The ESR of C1 = C2
≤
0.5Ω. Guaranteed by correlation, not production tested.
