ADP121-AUJZ28R7

ADP121 is a quiescent current, low dropout, linear regulator. The low 135mV dropout voltage at 150mA load improves efficiency and allows operation over a wide input voltage range. The low 30μA of quiescent current at full load make the device ideal for battery-operated portable equipment. It delivers good transient performance with minimal board area. Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. It is widely used in application such as mobile phones, digital cameras and audio devices, portable and battery-powered equipment, post dc-to-dc regulation, post regulation etc.
