The L4918 combines both a voltage regulator and a filter to provide high ripple rejection over a wider input voltage range. It has features such as high ripple rejection, high load regulation, high line regulation, short circuit protection, thermal shutdown, and dump protection.
The L4918 is a voltage regulator that combines a filter and a voltage regulator to provide high ripple rejection over a wider input voltage range. It features a supervisor low-pass loop that prevents the output transistor from saturating at low input voltages, allowing for a fast setting of the filter. The device includes protection features such as short circuit protection and thermal shutdown with hysteresis.
