MAX5084/MAX5085 65V, 200mA, Low-Quiescent-Current Linear Regulators in TDFN General Description Features The MAX5084/MAX5085 high-voltage linear regulators Wide Operating Input Voltage Range (6.5V to 65V) operate from an input voltage range of 6.5V to 65V and Thermally Enhanced 3mm x 3mm 6-Pin TDFN deliver up to 200mA of output current. These devices Package Dissipates 1.905W at +70C consume only 50A (typ) of quiescent current with no load Guaranteed 200mA Output Current and 6A (typ) in shutdown (EN pulled low). Both devices 50A No-Load Supply Current include a SET input, which when connected to ground, Preset 3.3V, 5.0V, or Adjustable (from 2.54V to 11V) selects a preset output voltage of 5V (MAX5084) or Output Voltage 3.3V (MAX5085). Alternatively, the output voltage can be adjusted from 2.54V to 11V by connecting the SET pin to Remote Load Sense the regulators output through a resistive divider network. Thermal and Short-Circuit Protection The MAX5084/MAX5085 also include an OUT SENSE -40C to +125C Operating Temperature Range pin, which allows remote voltage sensing right at the SET Input for Adjustable Output Voltage load, thus eliminating the voltage drop caused by the line Enable Input impedance. Both devices are short-circuit protected and include thermal shutdown. Ordering Information The MAX5084/MAX5085 operate over the -40C to PIN- +125C automotive temperature range and are available PART TOP MARK PACKAGE in a space-saving 3mm x 3mm thermally enhanced 6-pin MAX5084ATT+T 6 TDFN-EP* AJI TDFN package.
