BA33C25FP/HFP is a 2-output LDO series regulator IC.
Output current is 1A at maximum and output voltage
accuracy is +/-2%. This IC incorporates over-current
protection and thermal protection circuits.
1) 3.3V/1A, 2.5V/1A
2) Output voltage accuracy: +/-2%
3) PNP output and LDO voltage type
4) Built-in output current limit circuit protects the IC
from destruction by short
5) Built-in temperature protection circuit protects the IC
from thermal destruction by overload state
6) TO252-5 package, HRP-5 package
