To reduce standby current of an ECU that operates even when a vehicle is parked and the engine is turned off, it is essential to select power ICs and main components such as the MCU with low self-current consumption.

The S-19317/8 Series achieves the self-current consumption of 3.0μA typ, which is optimal for reducing the standby consumption of ECU. In addition, the Enable (EN) Pin allows the entire IC to be put into standby.

A power supply IC for an automotive device is connected to the IG (ignition) power supply and must provide stable power with excellent transient response even under drastic load and voltage fluctuations.
S-19311/2 Series responds to this need.

・Load transient response:
     About 3.5 times* (When I_OUT = 0.1mA→100mA)
     About 2.0 times* (When I_OUT = 100mA→0.1mA)

*When compared to S-19318 Series

The rising level of functionality of MCUs and automotive devices has led to the amount of current required. Power supply ICs capable of delivering high current have become in great demand.
The S-19317/8 and S-19311/2 Series support 200mA, 250mA, 400mA, and 500mA output currents, and are also available in high-power dissipation packages. This allows customers to choose the ideal regulator that fits their specific application.
