Low Power


Low-Power Voltage Reference

The present reference is a special application of current source IC Type LM334. It has a tiny temperature coefficient and draws only a minute current: at room temperature, only 10 µA, which increases with large rises in temperature by only a few µA. The circuit is basically a bandgap reference, because the positive temperature coefficient […]


Active Noise Cancelling ICs

Active Noise Cancelling ICs austriamicrosystems, a leading global designer and manufacturer of high-performance analog ICs, announced two new additions to its Active Noise Cancelling (ANC) IC family for improved hearing in noisy environments. Both the AS3400 and AS3420 feature the lowest power available, resulting in at least 20% longer battery life than other ANC solutions. […]

The new Si446x EZRadioPRO® transceiver family’s combination of superior RF performance and ultra-low power consumption makes it an ideal solution for […]


Low Power Cortex-M0 and EEPROM

Low Power Cortex-M0 and EEPROM NXP Semiconductors N.V. (released the LPC1100XL microcontrollers series featuring extra-low power. With the industry’s lowest active power consumption at 110 uA/MHz and reduced deep sleep current below 2µA, the LPC1100XL has set a new benchmark for low-power ARM® Cortex™-M0 microcontrollers. Also today, NXP announced the new LPC11E00 series for space-constrained […]


Low Power 12V Transformerless Power Supply

Many circuits can be powered directly from the mains with the aid of a series capacitor (C1). The disadvantage of this approach is that usually only one half cycle of the mains wave-form can be used to produce a DC voltage. An obvious solution is to use a bridge rectifier to perform full-wave rectification, which […]

Ultra Low-Power 5V Regulator

The current drain of the regulator is minute compared with that of, say, a 78L05: at an input voltage of 9 V and open-circuit output, it is just under 50 µA. The circuit consists of a straightforward bandgap reference based on T1 and IC1, followed by an amplifier formed by IC2 and T1. The reference […]
