Pinout
The MIC2920A-5.0WS is a fixed-voltage linear voltage regulator. It typically comes in a 5-pin TO-263 package. The pin functions are as follows:
1. Pin 1 (VIN): Input voltage supply. This is where the unregulated input voltage is applied.
2. Pin 2 (GND): Ground. This pin is connected to the ground of both the input and output circuits.
3. Pin 3 (VOUT): Output voltage. This pin provides the regulated output voltage.
4. Pin 4 (ERROR): Error flag output. It signals if the output voltage is out of regulation (e.g., due to overcurrent or thermal shutdown).
5. Pin 5 (SHUTDOWN): Shutdown input. When this pin is driven low, the regulator turns off, reducing the current consumption to a few microamperes.
This IC is designed for applications requiring a regulated 5.0V output, with a maximum output current of 400mA. It features low dropout voltage and low quiescent current, making it suitable for battery-powered devices.
