Pin Configuration

MIC2164-3YMM features an 8-pin MSOP package with the following pin configuration:

1. EN (Enable)
2. GND (Ground)
3. FB (Feedback)
4. VOUT (Output Voltage)
5. VIN (Input Voltage)
6. NC (No Connection)
7. NC (No Connection)
8. VOUT (Output Voltage)

Functional Features

• Enable Pin (EN): This pin allows the user to enable or disable the voltage regulator. When EN is high, the regulator is enabled and provides a regulated output voltage. When EN is low, the regulator is disabled, resulting in a low quiescent current.

• Feedback Pin (FB): The FB pin is used to set the desired output voltage level. By connecting an external resistor divider network between the output voltage and ground, the output voltage can be adjusted according to the application requirements.

• Thermal Shutdown Protection: MIC2164-3YMM incorporates thermal shutdown protection, which prevents the device from overheating by shutting down the regulator when the temperature exceeds a certain threshold.

• Short-Circuit Protection: The voltage regulator is equipped with short-circuit protection, ensuring that excessive current flow due to a short circuit does not damage the device.

Advantages and Disadvantages

Advantages

• Wide input voltage range allows for flexibility in various applications.
• Low dropout voltage ensures efficient power conversion.
• Low quiescent current minimizes power consumption.
• High PSRR reduces noise and ripple in the output voltage.
• Thermal shutdown and short-circuit protection enhance reliability.

Disadvantages

• Limited maximum output current may not be suitable for high-power applications.
• The 8-pin MSOP package may require additional space on the PCB compared to smaller packages.

Working Principles

MIC2164-3YMM operates as a linear voltage regulator. It uses a pass transistor to regulate the output voltage based on the feedback received from the FB pin. The internal circuitry compares the feedback voltage with a reference voltage and adjusts the pass transistor accordingly to maintain a stable output voltage.

When the enable pin (EN) is high, the regulator is active, and the output voltage is regulated. If the enable pin is low, the regulator enters a low-power mode with minimal quiescent current.
