Package

The WL2810D33-4/TR is packaged in a SOT-23 form factor, which is a small, surface-mount package commonly used for low-power devices.

Pinout

The WL2810D33-4/TR is a low-dropout linear voltage regulator (LDO) with a pin count of 4.
Pin Functions:
1. Input (Vin) - This pin is where the input voltage is applied, typically a higher voltage than the output.
2. Ground (GND) - The reference ground for the device, providing a common return path for current.
3. Output (Vout) - This pin delivers the regulated output voltage, which in this case is 3.3V.
4. Enable (EN) - This pin is used to enable or disable the output. When high, the regulator is active; when low, the output is disabled.
The WL2810D33-4/TR is designed for low power applications and provides excellent transient response, making it suitable for powering digital circuits and other devices requiring stable voltage.
