Requirements of devices
that operates when a vehicle is parked and the engine is off
Reduce standby current through intermittent operation
to minimize system operation.
Ensure stable operation
even under light load.
The S-19310 Series resolves these issues
The S-19310 Series of LDOs comes with reset function.
The world’s lowest current consumption, outstanding power supply capability support stable operation and low current consumption during intermittent operation.

The world’s lowest current consumption for building ECUs with ultra-low consumption
The low current consumption of intermittent operation helps reduce ECU standby current
The intermittent operation is effective way to reduct the standby current of ECU.
To further reduce the standby current of ECU, the current consumption of the always-on power IC during intermittent operation must also be low.
The S-19310 Series achieves the world’s lowest self-current consumption of 2.2μA typ. When used for powering the timer IC that controls an intermittent operation system, it helps reduce the standby current of ECU.
The high-withstand voltage of 45V means the LDO can be directly connected to a 12V battery.
Enables stable operation even under light load
In conventional power supply ICs, light load would cause the output voltage to rise which could sometimes damage downstream devices.
The S-19310 Series can maintain a stable output voltage even during almost 0 load conditions.
"An ultra-low current consumption" intermittent operation system integrating a convenience timer IC
You can safely leave power supply and monitoring of intermittent operation to the S-19310 Series and the timer function to the S-35710M A Series (convenience timer IC with built-in quartz oscillator).
This combination of components lowers standby current consumption to 2.4μA during intermittent operation.
ABLIC’s ICs strongly support the building of intermittent operation systems with ultra-low current consumption.
Proposing the series that best suits your monitoring needs
You can now select the LDO series that best suits your monitoring needs.
The S-19310 Series monitors the output voltage of the built-in LDO voltage regulator.
It is ideal for powering and monitoring devices that need a stable input voltage at startup.
