STMicroelectronics LD2985AM33R Low Drop Voltage Regulator

The LD2985AM33R from STMicroelectronics is a high-performance, low drop voltage regulator that is designed to provide a stable and reliable power supply for sensitive electronic circuits. This voltage regulator offers a fixed output voltage of 3.3V, which is ideal for powering low-voltage digital and analog devices.

With an ability to deliver up to 150 mA of output current, the LD2985AM33R is suitable for a wide range of applications, including battery-powered equipment, portable devices, and microcontroller systems. The low dropout voltage of just 120 mV at 150 mA load ensures efficient operation even when the input voltage is close to the output voltage, making it an excellent choice for applications with a tight power budget.

The LD2985AM33R incorporates several features that enhance the performance and safety of the powered device. These include thermal shutdown, which protects the regulator from overheating, and short-circuit protection, which safeguards both the regulator and the load in the event of a fault. Additionally, the low noise performance and low quiescent current make this regulator particularly suitable for noise-sensitive applications such as audio or RF systems.

This regulator comes in a robust SOT-23-5 package, which is not only space-saving but also allows for efficient heat dissipation. The small footprint of the component makes it an excellent choice for compact PCB layouts where space is at a premium.

Key features of the LD2985AM33R include:

• Fixed output voltage of 3.3V
