Pinout

The LP2992IM5-3.3 is a low-dropout linear voltage regulator with a fixed output voltage of 3.3V. It is commonly used in applications requiring efficient voltage regulation with low noise and low dropout voltage characteristics.
This device is available in a 5-pin SOT-23 package. The pin functions are as follows:
1. VOUT (Pin 1): This is the regulated output voltage pin. It provides the stabilized 3.3V output.
2. GND (Pin 2): The ground pin is the common return path for both the input and output.
3. SHDN (Pin 3): This is the shutdown pin. When pulled low, the regulator enters a low-power shutdown mode. If not used, it should be connected to the input voltage to enable normal operation.
4. VIN (Pin 4): This is the input voltage pin, where the unregulated input voltage is supplied. The input voltage should be higher than 3.3V to maintain regulation.
5. BYPASS (Pin 5): This pin is used to connect an external capacitor to reduce output noise and enhance transient response.
The LP2992IM5-3.3 is known for its low dropout voltage, low quiescent current, and ability to provide a stable output in various conditions, making it suitable for battery-powered and noise-sensitive applications.
