VNI4140K-32

The VNI4140K-32 is a high-performance, low-power, and low-dropout (LDO) linear voltage regulator manufactured by STMicroelectronics. It is designed to provide a stable and reliable output voltage in a wide range of input voltage and load current conditions. The LDO is available in a small SOT-23 package, making it suitable for space-constrained applications.

Description:

The VNI4140K-32 is a fixed-output LDO that provides an output voltage of 3.2V. It has a very low dropout voltage, which means it can operate efficiently even when the input voltage is close to the output voltage. The LDO also features a low quiescent current, which helps to minimize power consumption in battery-powered applications.

Features:

1. Fixed output voltage of 3.2V.
2. Low dropout voltage (LDO) for efficient operation under various input voltage conditions.
3. Low quiescent current (Iq) to minimize power consumption in battery-powered applications.
4. Small SOT-23 package for space-constrained applications.
5. Short-circuit protection to prevent damage in case of a short circuit at the output.
6. Thermal shutdown protection to prevent overheating.
7. Enable function to turn the LDO on or off, allowing for power management in the system.

Applications:

The VNI4140K-32 LDO is suitable for a wide range of applications that require a stable and reliable output voltage. Some of the potential applications include:

1. Portable electronic devices: Smartphones, tablets, and wearable devices.
