BA3258HFP Introduction

The BA3258HFP is an industry-grade, low cost, single-chip, high current LDO Regulator, which has an input voltage of 14V max, this IC features dual output stage. It can produce two regulated output voltages one 3.3V, and one 1.5V from a single input. This is a very space-efficient LDO that comes in an HRP5 package.

The BA3258HFP has a quiescent current of 10mA with an operating temperature range from -40°C to +125°C. BA3258HFP is generally used in include FPDs, TVs, DSPs, DVDs, and other battery-Powered Equipment’s.

How to use the BA3258HFP LDO Regulator

BA3258HFP low dropout regulator comes in 5 and package in 2 pins are output voltage pins. Supply the input voltage to the V-in pin and we get the regulated 3.3V 1.5V at the output pins. The input and output capacitors are used for ripple filtering. Connect a ceramic capacitor with a capacitance of approximately 3.3μF between VCC and GND close to the pins. Also, connect a 1µf capacitor between Vo and GND pins in order to prevent output oscillation.

Applications

• Battery-Powered Equipment
• FPDs, TVs, DSPs, DVDs
• Consumer/Personal Electronics
• High-Efficiency Linear Power Supplies
