Description
BA3259HFP is a power supply IC in which
2-output series regulators are incorporated
into a power package (HRP-5). 2-outputs
are 3.3V and a variable output. (It can be set
between 0.8V and 3.3V.) Each current is 1A.
Ceramic capacitor is available for output.
Features
1) 3.3V/1A and Variable(0.8V standard)/1A
2) Output ceramic capacitor available
3) Output voltage accuracy :+/-2%
4) Built-in over-current and thermal protection circuit
5) HRP-5 package
