Package
The LP5907SNX-3.3 is packaged in a small 5-pin SOT-23 (SOT-23-5) configuration. This allows for a compact design suitable for space-constrained applications.
Pinout
The LP5907SNX-3.3 is a low-dropout (LDO) voltage regulator with a pin count of 5. The pin functions are as follows:
1. IN (Input): This pin receives the input voltage, which should be higher than the desired output voltage (3.3V in this case).
2. GND (Ground): This pin is connected to the ground of the circuit.
3. OUT (Output): This pin provides a regulated output voltage of 3.3V.
4. EN (Enable): This pin is used to enable or disable the output. A high signal turns the regulator on, while a low signal turns it off.
5. NC (No Connect): This pin is not connected internally and can be left floating.
The LP5907SNX-3.3 is designed for applications requiring a stable output voltage with low noise and high power supply rejection.
