The L4922 is a high current monolithic voltage regulator with a very low voltage drop (maximum 0.9V at 1A, TJ = 25°C) that remains low over the entire operating temperature range (-40°C to +125°C). The device has low quiescent current (maximum 70mA at 1A) over the full temperature range, precise output voltage (5V ± 4%) over the full temperature range, power on-off information with set-table delay, reverse battery protection, short circuit protection, and thermal shutdown.
The L4922 is a high-current monolithic voltage regulator designed for automotive and industrial applications. It features a very low voltage drop of 0.70V maximum at 1A and includes internal protections against load dumps, reverse polarity, overheating, and output short circuits. The device operates over a temperature range of –40°C to +125°C.
