STMicroelectronics LD1117DT18 Voltage Regulator

The LD1117DT18 from STMicroelectronics is a robust and reliable low-dropout voltage regulator designed to provide a fixed 1.8V output voltage with a wide variety of input voltages ranging from 2.7V to 15V. This makes it an ideal component for a broad range of electronic applications, particularly where a stable voltage is crucial for the performance and longevity of the electronic circuitry.

With its ability to deliver up to 800mA of output current, this voltage regulator is well-suited for supplying power to low-voltage microcontrollers, memory devices, and other digital ICs. The LD1117DT18 comes in a TO-252 (DPAK) surface-mount package, which is compact and suitable for high-density PCB designs.

The device includes several features that ensure the protection and stability of both the regulator and the powered application. These features include thermal overload protection, which shuts down the regulator if the internal temperature exceeds safe operating limits, and short-circuit protection, which helps to prevent damage from output overload conditions. Additionally, the low dropout voltage minimizes power loss and improves efficiency, making it a great choice for battery-powered devices.

Key specifications of the LD1117DT18 include:

• Output Voltage: 1.8V
• Output Current: Up to 800mA
• Dropout Voltage: Typically 1.1V at 800mA
• Input Voltage Range: 2.7V to 15V
• Package: TO-252 (DPAK)
• Operating Temperature Range: -40°C to 125°C

The LD1117DT18 is not only efficient and versatile but also easy to implement in various circuit designs due to its minimal external component requirements. A simple capacitor on the input and output terminals is typically sufficient for stability, making it a straightforward choice for designers looking to streamline their power management solutions.

Whether you're developing consumer electronics, industrial control systems, or portable devices, the STMicroelectronics LD1117DT18 voltage regulator is an excellent choice for ensuring a stable and reliable power supply in your applications.
