General Description
The MAX5023/MAX5024 high-voltage linear regulators operate from a +6.5V to +65V input voltage and deliver up to 150mA of output current. These devices consume only 60µA of quiescent current with no load and with stand a -60V reverse-battery voltage at the input. The MAX5023/MAX5024 include an active-low internal microprocessor (µP) reset circuit that asserts when the regulator output drops below the preset output voltage
threshold by 7.5% or 12.5%, depending on the device selected. Both devices are available with a fixed +3.3V
or +5V output. These devices are short-circuit protected and include thermal shutdown.
