MAX5087 65V, 400mA, Low-Quiescent-Current Linear Regulator with Adjustable Reset Delay The MAX5087 high-voltage linear regulator operates from an input voltage of 6.5V to 65V and delivers up to 400mA of output current. The device consumes only 70µA of quiescent current with no load and 11µA in shutdown. The device includes a SET input, that when connected to ground, selects a preset output voltage of 3.3V MAX5087A or 5.0V MAX5087B . Alternatively, the output voltage can be adjusted from 2.5V to 11V by simply connecting SET to the regulator’s output through a resistive divider network. The MAX5087 also provides an open-drain, active-low microprocessor µP reset output that asserts when the regulator output drops below the preset output voltage threshold. An external capacitor programs the reset timeout period. Other features include an enable input, thermal shutdown, and short-circuit protection. The MAX5087 operates over the automotive temperature range of -40°C to +125°C and is available in a 16pin or a 56-pin TQFN thermally enhanced package.
