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

NOTE 2: In the test circuit capacitors C1 and C2 are 150

µF, 0.2 maximum ESR, tantalum or 22µF, 0.2

maximum ESR, tantalum. 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 Capacitor Selection section.

NOTE 4: Typical value indicates start-up voltage.
