The LM53600-Q1 and LM53601-Q1 devices are wide-input voltage range, low quiescent current, high-performance regulators with internal compensation designed specifically for the automotive market. These devices are designed to minimize end product cost and size while operating in demanding automotive environments. Normal operating frequency is 2.1 MHz allowing the use of small passive components. State of the art current limit allows the use of inductors that are smaller than those typically used in a 650mA or 1000mA regulator. 2.1MHz is above the AM band, allowing significant saving in input filtering. This part has a low unloaded current consumption eliminating the need for an external back-up LDO. The low shutdown current and high maximum operating voltage of the LM53600-Q1 and LM53601-Q1 devices also allows the elimination of an external load switch. To further reduce system cost, an advanced reset output is provided, which can often eliminate the use of an external reset or supervisory device.
The LM53600-Q1 and LM53601-Q1 devices are AEC Q1 qualified, and also have electrical characteristics ensured up to a maximum junction temperature of 150°C.
