Package

The LP5900SD-3.3 is available in a small 5-pin SOT-23 package type.

Pinout

The LP5900SD-3.3 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 connects to the input voltage supply, typically higher than the output voltage (3.3V in this case).
2. Ground (GND): This pin is connected to the system ground.
3. Output (Vout): This pin provides the regulated output voltage of 3.3V.
4. Enable (EN): This pin is used to enable or disable the regulator; pulling it high turns the device on, while pulling it low turns it off.
5. Bypass (BP): This pin is used to connect a capacitor for noise bypassing, improving output stability and performance.
The LP5900SD-3.3 is known for its low noise, high PSRR, and efficient performance in powering various electronic devices.
