STMicroelectronics LD1117V Linear Voltage Regulator

The LD1117V from STMicroelectronics is a robust linear voltage regulator designed to provide a stable output voltage with a low dropout. It is a versatile component, commonly used in a wide range of electronic applications where voltage regulation is critical. With its ability to deliver up to 800mA of continuous output current and its low dropout performance, the LD1117V is ideal for battery-powered devices, microcontroller systems, and other portable electronics.

Key Features:

• Low Dropout Voltage: The LD1117V offers a low dropout voltage, which means it can regulate the output voltage even when the input voltage is very close to the output voltage, enhancing efficiency in the system.
• Output Current: Capable of providing up to 800mA of output current, it is suitable for a broad range of applications that require a moderate amount of power.
• Adjustable Output: This regulator can provide a fixed output voltage, but it also allows for an adjustable output voltage, giving designers flexibility in their circuit designs.
• Thermal Overload Protection: The device includes thermal overload protection, which shuts down the regulator if the internal temperature exceeds safe operating limits, thereby protecting the device from damage.
• Short Circuit Protection: It also features short-circuit protection to prevent damage in the event of a fault or an incorrect connection.
• Wide Range of Output Voltages: The LD1117V is available in several fixed output voltages, including popular values like 1.8V, 2.5V, 3.3V, and 5V, as well as an adjustable version that can be set with external resistors.
