The NCV47411PAAJGEVB is an advanced linear voltage regulator with programmable output voltage accuracy, and allows the user to optimize for total system performance. This evaluation board is an effective tool for system engineers who are implementing precise linear voltage regulation and system-level power requirements. The board provides precise performance and capability for a wide variety of applications, including automotive, medical, and industrial.

The NCV47411PAAJGEVB is a low-dropout voltage (LDO) linear regulator with two selectable voltage references. The first reference is an external reference voltage between +2V and +24V and the second reference is an internal reference voltage of +1.25V. The board features a programmable voltage accuracy between ±0.4% to ±2% with an integrated voltage error amplifier. Two output configurations are available - a 12V output with maximum current up to 600mA, or two high-side 12V outputs from separate channels with up to 500mA per channel.

The NCV47411PAAJGEVB board is designed to offer superior system performance, with high PSRR (Power Supply Rejection Ratio) and transient response.PSRR is the measure of a voltage regulator’s ability to reject disturbances on its input supply line. High PSRR means that the regulator will maintain its output voltage even when the input supply voltage varies. Transient response is the time it takes for the voltage regulator to recover its normal operating state when triggered by sudden changes in the power supply. The NCV47411PAAJGEVB board has a fast transient response for improved system performance.

The board features very low operating current with a typical operating current of 0.15uA at no-load conditions. This makes the board ideal for energy-sensitive applications, such as wearable and battery-powered devices. It also features a low shutdown current of 0.8uA which results in a very low quiescent power dissipation. Additionally, the board is designed with overcurrent protection and features a programmable current limit of between 200mA to 600mA.

The board also has a power-good signal indicator which will go low when the output voltage falls below the setpoint, as well as overvoltage protection which will provide a warning signal should the output voltage exceed the set output voltage by a preset amount. The board also features under-temperature protection which will assert the power good signal low if the junction temperature exceeds 130°C.

The NCV47411PAAJGEVB is an efficient and reliable linear voltage regulator that is an excellent choice for modern electronic systems. It offers superior performance, low operating current, fast transient response, programmable voltage accuracy, and a wide operating temperature range. Its combination of easy-to-use features makes it an ideal choice for automotive, medical, and industrial applications.
