Pinout
The LP2985IM5-4.0 is a low-dropout (LDO) voltage regulator produced by Texas Instruments. It comes in a SOT-23-5 package, which means it has 5 pins. Here are the functions of each pin:
1. Vout (Pin 1): This is the regulated output voltage pin, which provides a fixed output of 4.0V in this specific variant.
2. GND (Pin 2): Ground pin, which is the reference point for the input voltage and load.
3. VIN (Pin 3): Input voltage pin, where the unregulated input voltage is supplied.
4. EN (Pin 4): Enable pin. This pin is used to enable or disable the regulator. Pulling this pin high turns the regulator on, while pulling it low turns it off.
5. NC (Pin 5): No connection. This pin is typically not internally connected and can be used as a mechanical support point.
The LP2985IM5-4.0 is designed for powering small, low-voltage devices and offers a fixed output with low dropout voltage, making it suitable for battery-powered applications.
