Package

The LP2985IM5-4.0 is a low dropout (LDO) voltage regulator packaged in a SOT-23-5 form factor. This package type is compact, suitable for surface mounting, and typically used in space-constrained applications where efficient voltage regulation is required.

Pinout

The LP2985IM5-4.0 is a low-dropout (LDO) voltage regulator with a 5-pin configuration. Its primary function is to provide a stable 4.0V output voltage with a maximum output current of 150 mA.
The pin configuration is as follows:
1. VOUT (Pin 1): This is the output pin where the regulated 4.0V is supplied.
2. GND (Pin 2): This is the ground pin, used as a reference for input and output voltages.
3. SHDN (Pin 3): This is the shutdown pin. When connected to a low logic level, it disables the output, putting the regulator in a low-power shutdown mode. If not used, it should be connected to VIN to enable the regulator.
4. BYPASS (Pin 4): This pin is used to connect an external capacitor to improve noise performance and transient response.
5. VIN (Pin 5): The input pin where the unregulated input voltage is supplied. The input voltage must be higher than the desired output voltage for proper operation.
The LP2985IM5-4.0 is commonly used in applications requiring a stable 4.0V supply, such as portable devices and battery-powered equipment.
