ZLDO1117QK12TC Description

Short technical summary and product information.

The ZLDO1117QK12TC from Diodes Incorporated is an automotive-compliant 1A low-dropout positive linear voltage regulator. It provides a fixed 1.2V output voltage with a maximum input voltage of 18V. The regulator features a low dropout voltage of 1.35V at full load current, making it suitable for applications requiring well-regulated low-voltage supplies.

 

Key electrical characteristics include a quiescent current of 5 mA and a Power Supply Rejection Ratio (PSRR) of 80dB at 120Hz. Protection features include over-current, over-temperature, and short-circuit protection. The device operates within an ambient temperature range of -40°C to +105°C.

 

This regulator is available in a TO-252 (D-Pak) surface-mount package, suitable for automated assembly processes. It is designed for use in automotive applications and is AEC-Q100 qualified, supporting PPAPs and manufactured in IATF16949 certified facilities. The component is also RoHS3 compliant and Halogen/Antimony free.
