L7918CV Description

Short technical summary and product information.

The STMicroelectronics L7918CV is a three-terminal negative voltage regulator designed for a wide range of applications. It provides a fixed output voltage of -18V and can deliver an output current of up to 1.5A, provided adequate heat sinking is used. The device features built-in thermal overload protection and short circuit protection for enhanced reliability.

 

This regulator is available in a TO-220 package, suitable for through-hole mounting. Its output transition SOA protection further safeguards the device during operation. The L7918CV is useful for on-card regulation, simplifying power supply designs and eliminating distribution issues associated with single-point regulation. It is particularly suited for split power supplies when used with the L78xx positive standard series.

 

Key electrical characteristics include an input voltage rating of -35V, a typical voltage dropout of 1.1V at 1A, and a PSRR of 60dB at 120Hz. The operating temperature range is from 0°C to 125°C.
