Pinout
The MIC29502BU is a low dropout (LDO) voltage regulator with a pin count of 5. The pins and their functions are as follows:
1. Input (VIN): This pin is where the input voltage is applied, typically ranging from 3V to 30V.
2. Ground (GND): This pin connects to the system ground and is used for the reference point of the output.
3. Output (VOUT): This pin provides the regulated output voltage, which can be set to a desired value (typically 2.5V to 15V) based on external resistors.
4. Adjust (ADJ): Used for external voltage setting. It connects to a resistor divider to set the output voltage if the output is adjustable.
5. Enable (EN): A logic-level input that enables or disables the output. A high signal turns the regulator on, while a low signal turns it off.
This device is designed for applications requiring low noise and low dropout performance.
