NOTE 1: Specified output resistance is a combination of internal switch resistance and capacitor ESR.

NOTE 2: In the test circuit capacitors C1, C2 and C3 are 22µF, 0.05 maximum ESR, ceramic or 3.3µF, 0.05Ω

maximum ESR, ceramic. Capacitors with higher ESR may reduce output voltage and efficiency. Refer to Capacitor

Selection section.

NOTE 3: Specified output resistance is a combination of internal switch resistance and capacitor ESR. Refer to

Optimizing Capacitor Selection.
