Note1 : Keep ON/OFF pin open when not using ON/OFF control.

Note2 : Keep Trim pin open when not using adjustable output.

Note 3: P-Good (23pin) is a function for BSV-3.3S9R5D (DIP type) only.

Recommended capacitor

C1 = 0

μF to hundreds of μF

C2 = 0

μF to 200μF typ. 10000μF max.

C1: Not required as long as impedance is very low and lines between +Vin side and the converter are

connected thick and short. For high impedance, adding a capacitor of low ESR such as an organic

semiconductor solid capacitor or a multi-layered ceramic capacitor is recommended.

C2: Not required due to an internal output capacitor. A multi-layered ceramic capacitor placed on the

load side will be recommended to satisfy electrical characteristics (to reduce ripple noise).
