BD25HA5MEFJ-ME2

Introduction

BD25HA5MEFJ-ME2 is a linear voltage regulator control IC with 4 integrated low dropout (LDO) regulators. It has excellent line and load regulation characteristics, low operating current and low noise output. It is ideally suited for powering critical mixed-signal, linear and low power digital applications in notebooks and desktops.

Features

• Output voltage range: 0.8V - 5.0V with programmable offset
• Programmable output current limit up to 500mA
• Low output voltage noise (Q-typ.<30 µVrms)
• High transient response
• Enable/shutdown control
• Short-circuit, thermal overload, and current foldback protection

Application Field

The BD25HA5MEFJ-ME2 is widely applied in PC notebook, desktops and other digital applications needing low dropout, high current output and high stability with low noise. It is commonly used to power microprocessors, peripheral blocks and digital circuits in consumer, automotive and industrial applications.

Working Principle

The BD25HA5MEFJ-ME2 implements an internal reference and uses a band gap circuit to provide very stable operation, even over temperature or voltage variations. The output is then actively regulated to maintain the desired voltage, regardless of variations in input supply, temperature or load. An enable pin is provided to shut the device down when required. The device also features s short-circuit, thermal overload and current foldback protection to prevent damage due to excessive conditions.

Conclusion

The BD25HA5MEFJ-ME2 is an ideal voltage regulator control IC for powering critical mixed-signal, linear and low power digital applications in notebooks and desktops. It features excellent line and load regulation characteristics, low operating current and low noise output, short-circuit, thermal overload and current foldback protection, and enables/shutdown control. Therefore, if you need a highly reliable and efficient voltage regulator for your application, the BD25HA5MEFJ-ME2 is the ideal choice.
