Part Description: MAX5087 DS


Part Details:

19-3964; Rev 3; 2/08 45V, 400mA, Low-Quiescent-Current Linear Regulator with Adjustable Reset Delay MAX5087 General Description Features The MAX5087 high-voltage linear regulator operates Wide Operating Input Voltage Range (6.5V to 45V) from an input voltage of 6.5V to 45V and delivers up to Thermally Enhanced Package Dissipates 400mA of output current. The device consumes only 2.6W at TA = +70°C (16-Pin TQFN) 70µA of quiescent current with no load and 11µA in Guaranteed 400mA Output Current shutdown. The device includes a SET input, that when 70µA Quiescent Supply Current connected to ground, selects a preset output voltage of Preset 3.3V, 5.0V, or Adjustable 2.5V to 11V 3.3V (MAX5087A) or 5.0V (MAX5087B). Alternatively, Output Voltage the output voltage can be adjusted from 2.5V to 11V by Remote Load Sense Capability simply connecting SET to the regulator s output through Enable Input a resistive divider network. The MAX5087 also providesan open-drain, active-low microprocessor (µP) reset Integrated µP Reset Circuit with Programmable Timeout Period output that asserts when the regulator output dropsbelow the preset output voltage threshold. An external Thermal and Short-Circuit Protection capacitor programs the reset timeout period. Other fea- -40°C to +125°C Operating Temperature Range tures include an enable input, thermal shutdown, andshort-circuit protection. The MAX5087 operates over the automotive tempera- Ordering Information ture range of -40°C to +125°C and is available in a 16-pin TQFN thermally enhanced package.
