Dual Low Drop Out Regulator

BA3257FP/HFP

Description

BA3257FP/HFP is a power supply IC in which

2-output series regulators are incorporated into

a power package (TO252-5/HRP-5). 2-outputs

are 3.3V and a variable output.(Above 1.5V can

be set.) Each current is 1A. Ceramic capacitor

is available for output.
