L7818CV-DG Description

Short technical summary and product information.

The STMicroelectronics L7818CV-DG is a positive, fixed output linear voltage regulator IC designed for various power management applications. It delivers a stable 18V output voltage with a maximum output current of 1.5A. The device operates with an input voltage up to 35V and has a typical voltage dropout of 2V at 1A.

 

Key electrical characteristics include a quiescent current of 8 mA and a Power Supply Rejection Ratio (PSRR) of 53dB at 120Hz. Protection features such as over-temperature and short-circuit protection are integrated for enhanced reliability.

 

This component is housed in a TO-220-3 package, suitable for through-hole mounting. The operating temperature range is from 0°C to 125°C. The L7818CV-DG is a reliable choice for applications requiring a fixed positive voltage supply.

 

Environmental compliance includes RoHS3 compliance, MSL 1 Unlimited, and REACH Unaffected status, though these are based on existing database information with low confidence.
