Semtech has added a new product to its line of nanoSmart platform of low power, Low Dropout (LDO) regulators, the nanoSmart SC573. The nanoSmart platform regulators target applications for Internet of Things (IoT) sensors including Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology).
A consistent voltage output with low noise (100μVRMS) is necessary for low-power radio devices, such as LoRa-based sensors, to function without noise interference with radio information transmission. The new nanoSmart SC573 device’s low quiescent current (50μA) enables energy savings in everyday products by extending operating life for battery-powered IoT sensors up to 10 years. The IC is ideal for developers designing solutions for industrial and consumer applications including smart metering and smart building.
Semtech nanoSmart ultra-low power technology enables energy savings in everyday products. The nanoSmart LDO products support multiple energy accumulation technologies including thermal, RF and indoor and outdoor solar. The platform implements advanced system power management and has a real-time clock making it ideal for remote sensing and control applications
The new nanoSmart LDO is essential for low power devices that need continuous supply voltage. The combined functionality of low noise and energy savings makes nanoSmart the regulator of choice for LoRa-based applications, and consumer and industrial electronics. The new nanoSmart LDO is currently available in 2 voltages (3.3V and 1.8V) and is priced at $0.130 in volumes of 10,000 units. For additional information, visit the Semtech website.
