BA3258HFP

BA33Dxx series

●General 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

Output voltage accuracy:

±2%.

A ceramic capacitor can be used to prevent output

oscillation (BA3258HFP).
