ABLIC Inc. launches the S-1318 Series compact LDO regulator with world's top class low current consumption of 95nA! An ideal power supply for IoT and wearable devices that reduces current consumption to one-tenth of our conventional products!

ABLIC Inc. (President: Nobumasa Ishiai, head office: Chiba City, Chiba Prefecture, hereinafter “ABLIC”) today launched the S-1318 Series of low-current consumption LDO regulators (*1) for wearables and IoT devices.
The new S-1318 Series LDO regulator features a 5.5V input, 1.2 - 3.3V output, 95nA current consumption and 100mA output current. The current consumption of the S-1318 Series is a mere 95nA or about one-tenth of our conventional products placing it in the world's top class (*2) for low current consumption devices. This helps improve battery life by 25% (*3), providing longer operating time for battery-powered applications. In addition, the compact HSNT-4 (1010) (1.0mm x 1.0mm x 0.4mm) package housing the regulator reduces product footprint.
These features make the S-1318 Series ideal for use in IoT and wearable devices that demand low-power consumption, long continuous operation and compact size.

(*1) LDO regulator: A voltage regulator that is capable of operating at a low potential difference between input and output with negligible energy loss and enables a design that significantly reduces heat buildup.
(*2) Based on our research as of October 2018
(*3) Values obtained under our testing conditions
