that must operate with up to a 36 V input supply. The regulator is
suitable for systems with low noise and small form factor
requirements often encountered in automotive driver information
systems. The NCV890204 is capable of converting the typical 4.5 V to
18 V automotive input voltage range to outputs as low as 3.3 V at

eliminating the need for costly filters and EMI countermeasures.
The NCV890204 also provides several protection features expected in
Automotive power supply systems such as current limit, short circuit
protection, and thermal shutdown. In addition, the high switching
frequency produces low output voltage ripple even when using small
