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!

CHIBA, Japan–(BUSINESS WIRE)–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

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.
Based on our research as of October 2018
(*3) Values obtained under
our testing conditions
