LM1117IMPX-ADJ Description

Short technical summary and product information.

The LM1117IMPX-ADJ from Texas Instruments is an 800-mA, low-dropout linear voltage regulator. This adjustable version allows the output voltage to be set from 1.25 V to 13.8 V using two external resistors.

 

Key electrical specifications include an output current capability of 800 mA, a line regulation of 0.2% maximum, and a load regulation of 0.4% maximum. The device features current limiting and thermal shutdown for protection. The operating temperature range for the LM1117I variant is -40°C to 125°C.

 

Packaged in a space-saving SOT-223 surface-mount package, the LM1117IMPX-ADJ is suitable for various applications requiring stable voltage regulation. A minimum of 10-µF tantalum capacitor is recommended at the output to enhance transient response.

 

This regulator is a reliable choice for power management in electronic designs where space and performance are critical. For newer alternatives with improved functionality, consider the TLV1117 or TLV761.
