LD1117ASTR Description

Short technical summary and product information.

The LD1117ASTR is a linear voltage regulator from STMicroelectronics with an adjustable positive output. It provides a maximum output current of 1A and an output voltage range from 1.25V to 15V, with a maximum input voltage of 15V. The regulator features a low dropout voltage of 1.3V at 1A load and a quiescent current of 5 mA. It offers a power supply rejection ratio (PSRR) of 80 dB at 120 Hz.

 

The device includes protection features such as over current and over temperature protection, ensuring reliable operation in various conditions. It operates over a temperature range of 0°C to 125°C.

 

The LD1117ASTR is housed in a surface-mount SOT-223 package (also referred to as TO-261-4, TO-261AA). It is available in tape and reel or cut tape packaging options. This regulator is suitable for applications requiring a stable adjustable voltage supply with moderate current capability.
