No.11026EBT01
●Description
The BA3258HFP, BA33D15HFP, BA33D18HFP are fixed 2-output low-saturation regulators with a voltage accuracy at both
outputs of 2%. These series incorporate both overcurrent protection and thermal shutdown (TSD) circuits in order to
prevent damage due to output short-circuiting and overloading, respectively.
●Features
1) Output voltage accuracy: 2%.
2) Output current capacity: 1A (BA3258HFP), 0.5A (BA33D□□ Series)
3) A ceramic capacitor can be used to prevent output oscillation (BA3258HFP).
4) High Ripple Rejection (BA33D□□ Series)
5) Built-in thermal shutdown circuit
6) Built-in overcurrent protection circuit
●Applications
FPDs, TVs, PCs, DSPs in DVDs and CDs
