... Detailed Description The MAX6791–MAX6796 ultra-low-quiescent-current, single-/dual-output, high-input-voltage linear regulators operate from 5V to 72V. The MAX6791–MAX6794 fea- ture dual regulators that deliver up to 150mA of load current per output. One output is available with preset output-voltage options (+1.8V, +2.5V, +3.3V, and +5.0V) and can be adjusted to any voltage between +1 ...

... Forcing ENABLE1/ENABLE low and HOLD high or unconnected places the MAX6791–MAX6796 into shut- down mode in which the MAX6791–MAX6796 draw less than 27µA of supply current. Table 3 shows the state of the regulator output with respect to the voltage level at ENABLE1/ENABLE and HOLD ...

... R1, R2 ≤ 200kΩ. where V SET Available Output-Current Calculation The MAX6791–MAX6794 provide up to 150mA per out- put, and the MAX6795/MAX6796 provide up to 300mA of load current. Since the input voltage can be as high as +72V, package power dissipation limits the amount of output current available for a given input/output volt- age and ambient temperature ...

... One way to disable the watchdog timer is to drive WD-DIS low for the MAX6793–MAX6796 and drive WDS0 high and WDS1 low for the MAX6791/MAX6792. Another method of disabling the watchdog timer is to pull CSWT low with an open-drain driver stage. This ...
