Advanced Monolithic Systems AMS2954
The AMS2954 series are micropower voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current (typ.75µA), and very low dropout voltage (typ.50mV at light loads and 380mV at 250mA) thus prolonging battery life. The quiescent current increases only slightly in dropout.| Part No. | AMS2954 |
