ABLIC Launches the S-19310/S-19315/S-19316 Series of Automotive LDO Voltage Regulators with a Voltage Monitoring Function

The world’s lowest (*1) self-current consumption, high-withstand voltage and high-speed voltage monitoring function enable building automotive ECUs with ultra-low current consumption

ABLIC Inc. launched the S-19310/S-19315/S-19316 Series of automotive LDO voltage regulators with a voltage monitoring function.

The S-19310/S-19315/S-19316 Series are automotive single-chip power supply (LDO voltage regulator) ICs with a power supply voltage monitoring function. These ICs are ideal for powering timer ICs that operate under low current.

The new power supply ICs launched today offer the world’s lowest self-current consumption, and also meet the requirements for ultra-low standby current.
The output voltage of conventional general-purpose LDO voltage regulators rise at high temperatures and light load, which can damage connected devices. These new ICs integrate functionality for suppressing rises in output voltage at high temperatures to ensure both low current and safety of timer ICs that operate under light load.

The S-19310 monitors the output voltage of the built-in LDO voltage regulator, the S-19315 monitors the voltage of the device connected to the SENSE pin, and the S-19316 monitors the input voltage of the built-in LDO voltage regulator. Since the detection voltage and the release voltage can be set independently within a specified range, optimum voltage monitoring can be set as required by each system.
It is designed to qualify for the AEC (Automotive Electronics Council)-Q100 Grade 1 standard for automotive ICs and is also PPAP (Production Part Approval Process) capable.
