Input voltage regulators that are specifically designed to maintain proper 1 CASE 369C 2. Ground 3 regulation with an extremely low inputtooutput voltage differential. 3. Output These devices are capable of supplying output currents in excess of 2 D PAK 100 mA and feature a low bias current of 0.4 mA at 10 mA output. D2T SUFFIX 1 CASE 936 Designed primarily to survive in the harsh automotive environment, 3 these devices will protect all external load circuitry from input fault SOT223 conditions caused by reverse battery connection, two battery jump ST SUFFIX 3 CASE 318H starts, and excessive line transients during load dump. This series also 1 includes internal current limiting, thermal shutdown, and additionally, is able to withstand temporary powerup with mirrorimage insertion. ADJUSTABLE OUTPUT VOLTAGE Due to the low dropout voltage and bias current specifications, the TO220 LM2931 series is ideally suited for battery powered industrial and TH SUFFIX consumer equipment where an extension of useful battery life is CASE 314A 11 desirable. The C suffix adjustable output regulators feature an output 5 inhibit pin which is extremely useful in microprocessorbased systems. TO220 1 TV SUFFIX Features Pin 1. Adjust 5 CASE 314B 2.
