IL2931AZ-5 LOW DROPOUT VOLTAGE REGULATORS TO - 92 The IL2931 series consists of positive fixed and adjust- able output voltage regulators that are specifically designed to maintain proper regulation with an extremely low input-to-output voltage differential. These devices are capable of supplying output currents in excess of 100 mA and feature a low bias current of 0.4 mA at 10 mA output. Designed primarily to survive in the harsh automotive environment, these devices will protect all external load circuitry from battery jump starts, and excessive line transients during load dump. This series also includes internal current limiting, thermal shutdown, and additionally, is able to withstand temporary power-up with mirror-image insertion. Pin 1. Input 2. Ground 3. Output Due to the low dropout voltage and bias current specifi cations, the IL2931 series is ideally suited for battery powered industrial and consumer equipment where an extens ion of useful battery life is desirable. The ‘C’ suffix adjustable output regulators feature an output inhibit pin which is extremely useful in microprocessor-based systems.
