MIC39501-2.5WU

The MIC39501-2.5WU is a low dropout (LDO) linear voltage regulator that was designed to provide up to 2.5 watts of output power. It is tailored to support portable applications and works in as low as 1.8V input voltage. With its advanced feature set, the MIC39501-2.5WU offers extreme flexibility to the user.

Application Field

The MIC39501-2.5WU is ideally suited for use in portable or mobile device applications, such as PDAs, cellular phones, digital cameras and global positioning systems. It is also a viable choice for applications with similar power requirements and space constraints such as PDAs and other wireless handheld products.

Specifically, it is capable of efficiently powering various LCD displays. It can provide up to 200 mA of current which makes it ideal for powering 1.6 inch and larger LCD displays. It is suitable for applications that require low output ripple, fast transient response and tight load regulation.

Furthermore, since the MIC39501-2.5WU supports multiple input and output voltages, users can easily adjust it to suit a wide variety of applications. It is designed with a low current operating range, enabling it to operate with numbers lows as just 5mA.

Working Principle

The MIC39501-2.5WU is a very simple and efficient linear voltage regulator. It works by connecting a low ESR ceramic capacitor from the input to ground to reduce input noise and then a capacitor from the output to ground to enable fast transient response. An inductor is used to reduce output ripple in order to provide clean and stable power.

The MIC39501-2.5WU includes a steady state transient control circuit, providing efficient operation with very fast response times. This feature also makes the MIC39501-2.5WU an ideal choice for high current applications. It uses an internal voltage reference, which can be externally adjusted using an optional external voltage source.

The MIC39501-2.5WU can handle up to 2.5 Watts of output power. When operating at this power, it will generate a predicted drop-out voltage of just 1.25 volts at an output current of 200mA. This is an advantage over many other linear voltage regulators, as it can offer improved output efficiency at higher output currents.

Additionally, the MIC39501-2.5WU offers protection from short circuits and over temperature conditions. This ensures the device operates reliably even in challenging environments.

Conclusion

The MIC39501-2.5WU is an excellent linear voltage regulator for applications requiring an efficient and reliable power supply. With its advanced feature set, it supports a wide variety of applications and is adjustable to meet users’ needs. In addition, its low dropout, fast transient response and protection features make it an ideal choice for today’s portable devices.
