Package

The LP5907MFX-1.8 is packaged in a 5-pin SOT-23 (TO-236) format. This compact surface-mount package is designed for low-power applications, providing efficient thermal performance and space-saving benefits for circuit board designs.

Pinout

The LP5907MFX-1.8 is a low-dropout (LDO) linear voltage regulator with a pin count of 5. Its primary function is to provide a stable output voltage of 1.8V from a higher input voltage, making it suitable for powering low-voltage digital circuits.
The pin configuration is as follows:
1. Input (VIN): Connects to the input voltage source.
2. Ground (GND): The reference ground for the device.
3. Output (VOUT): Provides the regulated 1.8V output.
4. Enable (EN): Controls the enable/disable state of the regulator. A high signal enables the output, while a low signal disables it.
5. Feedback/Bypass (FB): Used for output voltage regulation and can also be connected to a capacitor for improved performance.
This device is designed for low power applications, offers low quiescent current, and is ideal for battery-powered devices.
