MAX6795TPSD2+

高电压，微功耗，单/双路线性稳压器，带有监控功能 High-Voltage, Micropower, Single/Dual Linear Regulators with Supervisory Functions

The from Products is a high voltage, micropower, single linear regulator with supervisory functions in 20 pin TQFN package. This ultralow quiescent current, single output linear regulator has wide 5V to 72V operating input range, allowing it to withstand automotive load dump conditions while consuming only 68µA. It offers standard output voltage of 3.3V and can be adjusted to any voltage from 1.8V to 11V. The device features open-drain, active-low RESET output with a fixed output reset threshold that is 92.5%/87.5% of the regulator output OUT/OUT1. The reset output asserts low when OUT/OUT1 drops below the reset threshold and remains low for the fixed or capacitor adjustable reset timeout period after OUT/OUT1 exceeds the reset threshold. It provides a watchdog input that monitors a pulse train from the microprocessor µP and generates reset pulses if the watchdog input remains high or low for duration longer than watchdog timeout period.
