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.
1) 3.3V/1A and Variable(1.25V standard)/1A
2) Output ceramic capacitor available
3) Output voltage accuracy :+/-2%
4) Built-in over-current and thermal protection circuit
5) TO252-5 package and HRP-5 package
