Introduction

The MIC5200-5.0YMM-TR is a linear voltage regulator in the PMIC - Voltage Regulators - Linear category. It is designed for use in data converter systems, which require low noise outputs in the range of 0 to 5.0VDC. It is capable of providing up to 500mA of current with a low output ripple of typically 0.1%.

Application Field

The MIC5200-5.0YMM-TR is an ideal choice for use in high-performance data conversion systems, where low noise output voltages are required. It can also be used in a wide range of general purpose applications as well, such as powering circuits as well as a number of other system/circuit interface points.Its main application fields include the following:

• Data Converter Systems
• High-Performance Digital Circuits
• Powering Circuits
• Circuit/System Interface Points
• General Purpose Voltage Regulation

Working Principle

The MIC5200-5.0YMM-TR is an adjustable linear voltage regulator, meaning it operates on a basic principle of using a series of resistors, a diode, and a single voltage regulator to control the output voltage. The voltage regulator, in this case an LM voltage regulator, relies on the Base-Emitter voltage difference of an internal transistor and a zener diode for its precise voltage output. The actual circuit diagram of the regulator is a combination of the input, output, current limiting and temperature compensation resistors.

The MIC5200-5.0YMM-TR is a regulator that controls the output voltage by controlling the base-emitter voltage of the internal transistor. In basic terms, the regulator compares the output voltage with the voltage applied to its input pins (IN and GND), and produces an output voltage accordingly. If the output voltage is greater than that applied to the input, then the regulator will lower the output voltage by reducing the base-emitter voltage applied to the internal transistor. Conversely, if the output voltage is too low, the regulator will increase the output voltage by increasing the base-emitter voltage applied to the internal transistor.

The MIC5200-5.0YMM-TR also has temperature compensation circuitry built into the regulator to ensure precise operations at various temperatures. This is done by adding a zener diode to the circuit, whose reflect circuit action is determined by the voltage drop across it. The zener diode will adjust the voltage drop across the internal transistor to account for changes in temperature, ensuring the output voltage remains exactly at the desired level.

Lastly, the MIC5200-5.0YMM-TR has an adjustable current-limiting feature, which limits the amount of current that can pass through the regulator. This is a safety feature; if the regulator is overloaded, the current-limiting circuit will detect this excessive current flow and shut down the device, preventing further damage to the circuit.

Conclusion

The MIC5200-5.0YMM-TR is a linear voltage regulator in the PMIC - Voltage Regulators - Linear category. It is capable of providing up to 500mA of current with a low output ripple of typically 0.1%. It is designed for use in data converter systems, which require low noise outputs in the range of 0 to 5.0VDC. It has a basic operating principle of using a series of resistors and a diode, combined with an LM voltage regulator so as to precisely control the output voltage. It also has temperature compensation circuitry, along with a adjustable current-limiting feature, allowing the regulator to provide precise and reliable operation in a number of applications.
