Maxim's MAX6765-MAX6774 high-voltage, low-power linear regulators, can deliver up to 100 mA of output current, which is ideal for automotive and industrial applications. These low-power devices operate from 4 V to 72 V and consume only 31 μA of quiescent current, making them suitable for always-on applications such as automotive modules.
These devices are offered with a 1,5% accurate, fixed-output voltage of 5,0 V, 3,3 V, 2,5 V, or 1,8 V. Additionally, two external resistors enable the output voltage to be adjusted externally from 1,8 V to 11 V. Each device offers an internal reset circuit that asserts whenever the monitored output voltage falls below its respective threshold. When the output voltage exceeds its reset threshold, the device de-asserts after the reset timeout period. Reset timeouts are offered with fixed timeout options of 75 μs, 3 ms, 12,5 ms, 50 ms, or 200 ms or can be adjusted externally with a capacitor.
Half of this range is offered with an open-drain reset output, while the other half have a push-pull reset output. Some of these linear regulators also offer an enable and hold circuit, an adjustable reset input, dual enable inputs, and a watchdog timer. Additionally, all of these devices provide thermal and short-circuit protection.
The MAX6765-MAX6774 come in 3 x 3 mm TDFN package and are specified from -40 to 125°C.
