The MAX5086 high-voltage linear regulator operates from a 6.5V to 45V input voltage and delivers up to a 250mA output current. The device consumes only 70µA of quiescent current with no load and 13µA in shutdown. The device includes a SET input, that when connected to ground, selects a preset output voltage of 3.3V (MAX5086A) or 5.0V (MAX5086B). 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 MAX5086 also provides an open-drain, active-low microprocessor 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 MAX5086 operates over the automotive temperature range of -40°C to +125°C and is available in a 16-pin TQFN thermally enhanced package.

Product Detail

The MAX5086 evaluation kit (EV kit) allows the user to evaluate the features of the MAX5086 high-voltage linear regulator including the remote output-voltage sensing capability. This EV kit is a fully assembled and tested surface-mount board.

The MAX5086 EV kit supplies an output current of up to 250mA at a 3.3V or 5.0V output and operates up to a 45V input voltage. This EV kit also includes connections for the active-low microprocessor reset output and enable input.

Warning: The MAX5086 EV kit operates with high voltages. Dangerous voltages are present on this EV kit and on equipment connected to it. Users who power up this EV kit or power the sources connected to it must be careful to follow safety procedures appropriate to working with high-voltage electrical equipment. Under severe fault or failure conditions, this EV kit may dissipate large amounts of power, which could result in the mechanical ejection of a component or of component debris at high velocity. Operate this EV kit with care to avoid possible personal injury.
