LM201ADT

The LM201ADT is a low-dropout (LDO) linear voltage regulator manufactured by STMicroelectronics. It is designed to provide a stable and reliable voltage output for a wide range of applications.

Description:

The LM201ADT is a low-dropout linear voltage regulator that operates from an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 1.8V. It has a very low dropout voltage of 250mV, which means it can operate efficiently even when the input voltage is close to the output voltage. The device is available in a small SOT-23 package, making it suitable for space-constrained applications.
