Linear Regulators

Linear Regulators from Analog Devices offer customers superior performance in a variety of surface-mount industry-standard packages and include value-add features like thermal overload protection, over-current protection, under-voltage lockout (UVLO), low output noise, quick output discharge (QOD), and shutdown mode that drastically reduces current consumption. Analog Devices Low Drop Out (LDO) linear regulators offer fixed and adjustable output voltage options, up to 2.0 A of output current, and dropout voltages down to 80 mV.

Linear voltage regulators from Analog Devices are backed by online design support, tools and resources to help shorten your design time. Search 18 different parameters to select the best LDO regulator for your design with our handy parametric selection table. Get help and interact with fellow engineers and ADI power experts at the Power Support Community on EngineerZone™.
