STMicroelectronics L4931CPT33-TR Low Dropout Voltage Regulator

The L4931CPT33-TR from STMicroelectronics is a high-performance, low dropout voltage regulator designed to provide a stable and reliable power supply in a variety of applications. This device is particularly well-suited for battery-powered systems where energy efficiency is paramount. With an output voltage of 3.3V and a capability to deliver up to 250mA of output current, this regulator maintains a low dropout voltage even at full load, ensuring efficient operation and extended battery life.

The L4931CPT33-TR stands out with its very low dropout voltage of typically just 0.4V at 150mA of load current, which allows for better performance compared to traditional linear regulators, especially when the supply voltage is close to the output voltage. Additionally, the device features a very low quiescent current of 0.6mA (typical) in full-on mode, which drops to below 1µA when in shutdown mode, making it an excellent choice for power-sensitive designs.

One of the key advantages of the L4931CPT33-TR is its thermal overload protection, which safeguards the device and the application from damage due to excessive power dissipation. Furthermore, the regulator includes short-circuit protection and a limiting current feature, enhancing the safety and reliability of the system it's integrated into.

Designed with flexibility in mind, this voltage regulator comes in a TO-252 package, known for its small footprint and excellent power dissipation characteristics. This makes the L4931CPT33-TR a versatile solution that can be used in a wide array of applications, from automotive to consumer electronics, and from industrial controls to healthcare devices.
