Package

The LMBR140ET1G is packaged in a SOT-23 (Small Outline Transistor) package type. This surface-mount package is compact, suitable for various applications, and allows for easy integration into electronic circuits.

Pinout

The LMBR140ET1G is a low-voltage, low-dropout voltage regulator (LDO) from ON Semiconductor. It features a 5-pin package configuration, typically in a SOT-23 or similar package.
Pin functions are as follows:
1. Input (Vin): This pin is where the input voltage is supplied to the regulator.
2. Ground (GND): This is the ground reference pin for the device.
3. Output (Vout): This pin provides the regulated output voltage.
4. Enable (EN): This pin is used to enable or disable the output voltage. Pulling this pin high enables the regulator, while pulling it low disables the output.
5. Feedback (FB): This pin is used for feedback to ensure the output voltage remains stable and within specified limits.
The LMBR140ET1G is designed for applications that require a stable voltage supply with low dropout characteristics, making it suitable for portable devices and battery-powered applications.
