The NCV8161ASN280T1G is a positive voltage regulator featuring low quiescent current and maximum power saving at light loads. This linear regulator is part of the True Low-Dropout (LOD) linear regulators family developed for automotive, space-critical power management applications where space and weight are limiting factors. With its Optimization for Extremely Low quiescent Current (ORL) output, which is just 2.5 uA in the disabled state, this voltage regulator device is designed to be one of the mostSpace-efficient solutions available on the market. It offers very low on-resistance and provides maximum power savings through its high-efficiency features. This regulator features an adjustable output voltage range of 2.6 V to 6 V and can be used in a wide variety of applications, including automotive, battery-powered devices, and space-critical power management.

The NCV8161ASN280T1G is used in automotive, space-critical power management applications, offering a high level of reliability in terms of temperature, loads, and line conditions. This versatile linear regulator features on-board protection features such as inrush current limiting, over-current protection, and thermal shut down, to ensure reliable operation. The device is available in surface mount and through-hole mounting packages and is designed to meet AEC-Q100 (Grade 2) qualification.

The working principle of the NCV8161ASN280T1G linear regulator is simple. It is a three-terminal, positive-voltage regulator that uses a p-channel MOSFET as its reference to regulate the output voltage. The input is the unregulated voltage source and the output is the regulated voltage source. This regulator has a variable output voltage, so the resistor divider at the output pin of the regulator adjusts the voltage depending on the output voltage set by the user. The regulation circuit also includes a feedback control circuit that senses the output voltage and introduces a voltage error into the control circuit. This error signal then controls the gate of the p-channel MOSFET, which adjusts the output voltage of the regulator to maintain the set output voltage. To prevent the output voltage from dropping below the minimum regulated voltage, the device features an ORL (Optimization for Extremely Low quiescent Current) mode which limits the quiescent current to 2.5 uA.

In conclusion, the NCV8161ASN280T1G is a positive voltage regulator designed for automotive, space-critical power management applications. It provides high-efficiency, low-dropout operation, with maximum power savings at light load. It features an adjustable output voltage range of 2.6 V to 6 V, and is ideal for battery-powered devices and other space-critical applications. It features on-board protection features such as inrush current limiting, over-current protection, and thermal shut down, to ensure reliable operation, and is available in surface mount and through-hole mounting packages.
