LM2931CDR2 Description

Short technical summary and product information.

The LM2931CDR2 from On Semiconductor is a versatile adjustable LDO (Low Dropout) voltage regulator. It is specifically engineered to maintain regulation with a very low input-to-output voltage differential, making it ideal for battery-powered applications where extending battery life is crucial.

 

This device can supply output currents in excess of 100 mA and features a low bias current of 0.4 mA at 10 mA output. It is designed to operate reliably in harsh automotive environments, offering protection against reverse battery connection, jump starts, and excessive line transients during load dump. Internal current limiting and thermal shutdown provide additional protection.

 

The LM2931CDR2 is available in an 8-SOIC surface mount package, suitable for various electronic designs. Its adjustable output capability and low dropout voltage make it a flexible choice for power management in consumer and industrial equipment.

 

Key electrical characteristics include a voltage dropout of less than 0.6V at 100 mA and protection features such as over current and over temperature shutdown. The operating temperature range is from -40°C to 125°C.
