Description

The LD1117DT12TR is a voltage regulator from the LD1117 series, manufactured by STMicroelectronics. It is designed to provide a stable output voltage of 1.2 volts with a maximum output current of 800 mA. The part is typically used in applications that require a reliable power supply, such as microcontrollers, sensors, and other electronic components.
The "DT" in the model number indicates the package type, which is a DPAK (TO-252), a surface-mount package suitable for high-density circuit boards. The "TR" denotes that the component comes in tape and reel packaging, ideal for automated assembly processes.
The LD1117DT12TR offers features like low dropout voltage, typically around 1.1 volts at full load, and internal current and thermal limiting, ensuring protection from excessive currents and overheating. These features make it an efficient and reliable choice for low-power applications. Additionally, its low quiescent current and high output voltage accuracy contribute to its performance in various electronic circuits.

Pinout

The LD1117DT12TR is a low-dropout voltage regulator from STMicroelectronics. It typically comes in a DPAK (TO-252) package which has 3 pins plus a tab. The pin configuration and their functions are as follows:
1. Pin 1 (ADJ/GND): This pin is used as either the ground connection for the fixed-voltage version or the adjust pin for setting the output voltage in the adjustable version.
2. Pin 2 (VOUT): This is the output pin that provides the regulated voltage.
3. Pin 3 (VIN): This is the input pin where the unregulated input voltage is supplied.
4. Tab: The tab is connected internally to the ground (GND) for fixed versions or to the adjust pin for adjustable versions and is often used for heat dissipation as it can be mounted to a heatsink.
The LD1117DT12TR is specifically a 1.2V fixed output voltage version. It is designed to provide a stable 1.2V output with a maximum output current of 800mA.
