Introduction

The MIC5201-3.3BS TR is a Linear, Voltage Regulator PMIC (Power Management IC). It is a 3.3V low-dropout (LDO) input regulator that is specifically designed for the long-lasting, dependable, and efficient operation of powered devices in space-critical applications. The MIC5201-3.3BS TR features a dropout voltage of 250 mV, a low-noise output, and low power consumption—making it suitable for battery-powered applications.

Application Field

The MIC5201-3.3BS TR is a versatile 3.3V regulator ideal for portable applications, such as cell phones, digital cameras, PDAs, and hand-held computers. It is also suitable for other applications with tight space requirements, such as wireless communication systems.The wide input voltage range of this regulator is another great feature that makes it suitable for a wide range of applications. It can handle input voltages from 2.7V to 6.5V, allowing it to effectively regulate a wide range of input voltages from the battery or from DC/DC converters.

Working Principle

The MIC5201-3.3BS TR is an advanced linear voltage regulator that works by monitoring the differences between the input voltage and the output voltage. It then adjusts the current going through the device to try to keep the output voltage at the level set by the user.When the input voltage is greater than the output voltage, the transistor within the IC starts to increase its resistance. This reduces the amount of current flowing through the device, resulting in lower power consumption. When the input voltage is lower than the output voltage, the transistor’s resistance decreases, allowing more current to flow. This helps maintain a consistent output voltage.The MIC5201-3.3BS TR also features a built-in over-current protection that will shut off the device if it detects a current overload. This provides additional safety when the device is being used in systems with higher power requirements.

Conclusion

The MIC5201-3.3BS TR is a versatile and efficient 3.3V linear voltage regulator that is ideal for a wide range of applications, including portable devices and wireless communication systems. It supports a wide input voltage range and features a low-dropout design, low noise output, and low power consumption. It also features built-in over-current protection for additional safety.
