Introduction

The MIC5271YM5-TR is a family of high-performance 4A-2A low-dropout (LDO) linear voltage regulators (VREGs). These devices operate from wide input voltage range of 3V to 24V, while providing an adjustable output voltage range of 1.25V to 15V, with a typical dropout of 310mV at 4A (VIN-VOUT = 3.10V). The MIC5271YM5-TR is packaged in a miniature 10-pin ultra-small, space-saving (1.3mm x 1.3mm) micro TDFN package, allowing a higher power density, reduced board area and better thermal dissipation performance than most other VREGs. The MIC5271YM5-TR is designed to handle a wide range of applications including PoE, storage, networking and communication, automotive, industrial and medical together with many other applications that require high efficiency, small size, and low-dropout operation.

Application Field

The MIC5271YM5-TR is ideal for powering the latest high-speed digital circuits, where bandwidth and throughput are essential. These VREGs provide high power density and low power loss in ultra-small packages and support a wide input voltage range, with a low dropout voltage of 0.3V at 4A. As such, the MIC5271YM5-TR is perfect for applications requiring accurate, low-noise, low-dropout supply and output voltages, such as Point-of-Load, PoE, networking, WLAN & storage applications. Additionally, the device can be used in automotive and industrial applications, medical and healthcare applications, audio systems, battery-powered applications, and many other applications that require a high efficiency and small size.

Working Principle

The MIC5271YM5-TR is a linear voltage regulator designed to provide a regulated output voltage within a range of 1.25V to 15V. Its working principle is based on the voltage regulation principle, where the output voltage of the device is maintained at a preset level despite the variations in the load or input voltages. The voltage regulation is achieved by a negative feedback loop. A feedback resistor is connected between the output voltage and the error amplifier. The output voltage is compared to a reference voltage and an error signal is generated accordingly. This error signal is amplified and compared with a feedback signal from the output voltage. The difference between these two signals is amplified and then applied back to the output terminal in order to adjust the output voltage. The MIC5271YM5-TR includes a series of MOSFETs and a variable-gain operational amplifier which are used to accurately regulate the output voltage and provide efficient operation.

Conclusion

To sum up, the MIC5271YM5-TR is a high-performance 4A-2A low-dropout linear voltage regulator designed to handle a broad range of applications including PoE, storage, networking and communication, automotive, industrial and medical. It operates in a wide input voltage range of 3V to 24V, while providing an adjustable output voltage range of 1.25V to 15V, with a typical dropout at 4A being 310mV. The MIC5271YM5-TR includes a series of MOSFETs and a variable-gain operational amplifier which are used to accurately regulate the output voltage and provide efficient performance.
