MIC5247-2.0YD5-TR Application Field and Working Principle

The MIC5247-2.0YD5-TR is a precision dual 2A low dropout (LDO) regulator designed for use in portable and low power applications. The device offers regulated output current of up to 2A, a low dropout voltage of just 0.7V at full load current, and a wide input voltage range from 2.7V to 5.5V. It also features excellent transient response and low output noise.

The MIC5247-2.0YD5-TR is a 2A low-dropout (LDO) voltage regulator that is designed for use in a wide range of low-power, portable, and other demanding electronics applications. It provides highly accurate regulated output currents of up to 2A with a low dropout voltage of just 0.7V at full load current. The device is available in a tiny SOT-23 package and operates over a wide input voltage range of 2.7V to 5.5V. In addition, it is factory-trimmed to provide excellent output regulation and low output noise.

The device includes two independent 2A LDO circuits with adjustable output voltage settings of 1.2V and 2.5V, respectively. Each LDO circuit consists of a P-channel MOSFET and a current-limiting circuit so that the voltage drop across the device does not exceed 0.7V when the desired current is exceeded. This allows the device to maintain a constant output voltage during highly dynamic current load changes, ensuring high reliability and stability.

The MIC5247-2.0YD5-TR also features a wide input voltage range from 2.7V to 5.5V, allowing it to be used for a variety of applications. Its excellent transient response and low output noise characteristics make it an excellent choice for noise sensitive applications such as portable medical electronics, telecommunications, and battery-powered equipment. Its fast transient response also makes it suitable for automotive, DSL modem line, and general purpose applications.

In addition, the device\'s high ripple rejection coupled with its low dropout voltage of 0.7V ensures that it is able to maintain a reliable output voltage during varying input conditions. Furthermore, it includes over-temperature and over-voltage protection to ensure safe operation in the event of unexpected conditions.

Overall, the MIC5247-2.0YD5-TR is an ideal choice for applications which require ability to supply a stable current with a low dropout voltage and excellent noise performance, such as portable medical electronics, communication systems and battery-powered equipment.
