MAX5086A, MAX5086B

45V, 250mA, Low-Quiescent-Current Linear Regulator with Adjustable Reset Delay

250mA, 45V Input, Low-Quiescent-Current Linear Regulators in High-Power TQFN Packages


Please check latest availability status for a specific part variant.

Description

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.
