19-3928; Rev 0; 1/06 65V, 200mA, Low-Quiescent-Current Linear Regulators in TDFN General Description The MAX5084/MAX5085 high-voltage linear regulators operate from an input voltage range of 6.5V to 65V and deliver up to 200mA of output current. These devices consume only 50µA (typ) of quiescent current with no load and 6µA (typ) in shutdown (EN pulled low). Both devices include a SET input, which when connected to ground, selects a preset output voltage of 5V (MAX5084) or 3.3V (MAX5085). Alter.

19-3928; Rev 0; 1/06 65V, 200mA, Low-Quiescent-Current Linear Regulators in TDFN General Description The MAX5084/MAX5085 high-voltage linear regulators operate from an input voltage range of 6.5V to 65V and deliver up to 200mA of output current. These devices consume only 50µA (typ) of quiescent current with no load and 6µA (typ) in shutdown (EN pulled low). Both devices include a SET input, which when connected to ground, selects a preset output voltage of 5V (MAX5084) or 3.3V (MAX5085). Alternatively, the output voltage can be adjusted from 2.54V to 11V by connecting the SET pin to the regulator’s output through a resistive divider network. The MAX5084/ MAX5085 also include an OUT_SENSE pin, which allows remote voltage sensing right at the load, thus eliminating the voltage drop caused by the line impedance. Both devices are short-circuit protected and include thermal shutdown. The MAX5084/MAX5085 operate over the -40°C to +125°C automotive temperature range and are available in a space-saving 3mm x 3mm thermally enhanced 6-pin TDFN package. www.DataSheet4U.com Features ♦ Wide Operating Input Voltage Range (6.5V to 65V) ♦ Thermally Enhanced 3mm x 3mm 6-Pin TDFN Package Dissipates 1.905W at +70°C ♦ Guaranteed 200mA Output Current ♦ 50µA No-Load Supply Current ♦ Preset 3.3V, 5.0V, or Adjustable (from 2.54V to 11V) Output Voltage ♦ Remote Load Sense ♦ Thermal and Short-Circuit Protection ♦ -40°C to +125°C Operating Temperature Range ♦ SET Input for Adjustable Output Voltage ♦ Enable Input MAX5084/MAX5085 Applications Automotive Industrial Home Security Telecom/Networking PART Ordering Information TEMP RANGE PINPACKAGE TOP PKG MARK CODE AJI T633-2 AJJ T633-2 MAX5084ATT+T -40°C to +125°C 6 TDFN-EP* MAX5085ATT+T -40°C to +125°C 6 TDFN-EP* *EP = Exposed paddle. +Denotes lead-free package.
