Pinout
The pin configuration and functions are as follows:
1. Pin 1 (VOUT): Output pin that supplies the regulated 3.3V.
2. Pin 2 (GND): Ground connection.
3. Pin 3 (SHUTDOWN): Shutdown pin for enabling or disabling the regulator. If connected to ground, the regulator is enabled; if connected to a high voltage, the regulator is disabled.
4. Pin 4 (VIN): Input pin where the unregulated input voltage is supplied.
5. Pin 5 (BYPASS): Bypass pin for connecting an external capacitor to improve noise performance and transient response.
The LP2985IM5-3.3 is widely used in applications requiring a stable 3.3V output from a higher input voltage source, with low quiescent current and good noise performance.
