The TSL9A12 series are ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode with 600nA quiescent current at no load. The TSL9A12 series is ideally suited for standby micro-control-unit systems, especially for always-on applications like portable, and other battery-operated systems. The TSL9A12 series retains all the features that are common to low dropout regulators including a low dropout PMOS pass device, short circuit protection and thermal shutdown.
