Introduction

The MIC52xx series is a family of linear voltage regulators (VREG) manufactured by M-Integrity Technology Co., Ltd. The MIC5216-3.2YMM-TR is a single SMD voltage adjustable linear VREG that is operated over an input voltage range of 2.96V to 3.46V and produces a regulated output voltage of 3.2V +/-2%. The MIC5216-3.2YMM-TR offers high performance features such as ultra low dropout voltage, excellent line and load regulation, a wide output current range up to 150mA, excellent temperature stability (typically 0.05%/°C), and a programmable current limit. This device is ideal for supporting a variety of applications requiring a very low drift and tight voltage regulation for processor core and I/O supplies.

Applications

The MIC5216-3.2YMM-TR is designed to provide a 3.2V regulated voltage output with a wide range of input voltages. This makes the VREG suitable for a variety of applications with conflicting requirements such as point-of-load (POL) applications, low-voltage power supplies, or portable digital electronics.Mobile processors and digital base band Ethernet devices use POLs to improve power efficiency by localizing the power supply and eliminating wasteful cable losses. The MIC5216-3.2YMM-TR is an ideal solution for these applications as its wide input voltage range and ultra low dropout voltage offer superior efficiency and increased current output capability.The MIC5216-3.2YMM-TR is also well suited for low-voltage power supplies such as those found in consumer, industrial and automotive applications. The device can be used in isolated AC-DC power supplies, DC-DC converters, and automotive 12V and 24V DC-batteries.

Features

The MIC5216-3.2YMM-TR is designed to offer superior performance and features for a wide range of demanding applications. The device offers voltage regulation within +/-2% over line and load conditions, an ultra low dropout rating of 250mV, a wide operating temperature range of -40°C to +85°C, and a wide input voltage range of 2.96V to 3.46V. The device also has a programmable current limit output to prevent damage to the part should a current overload occur. This feature is especially useful in applications such as portable devices, battery powered equipment and automotive systems.

Working Principle

The MIC5216-3.2YMM-TR is a linear voltage regulator that uses a simple linear control circuit to regulate the output voltage. The device consists of a voltage reference and error amplifier, an output transistors, pass elements, a current limiting circuit, and a temperature compensation circuit.The voltage reference monitors the output voltage and provides a stable reference voltage for the error amplifier. The output voltage is compared to the reference voltage and any error is amplified and applied to the output transistors. An output pass element adjusts the output voltage by regulating the flow of current through the output transistors.The current limiting circuit monitors the output current and limits it to the programmed value to prevent damage to the device if an overload occurs. The temperature compensation circuit monitors the device temperature and adjusts the output voltage accordingly.

Conclusion

The MIC5216-3.2YMM-TR is a single SMD voltage adjustable linear voltage regulator that is ideal for providing a stable, regulated voltage output up to 3.2V over a wide range of input voltages. The device offers high performance features such as ultra-low dropout voltage, excellent line and load regulation, wide output current range up to 150mA and excellent temperature stability. The MIC5216-3.2YMM-TR is well suited for applications such as point-of-load, low-voltage power supplies, and portable digital electronics.
