The NCP4626DSN045T1G is a linear voltage regulator that falls under the group of PMIC (Power Management Integrated Circuit) devices. It is an advanced low-dropout regulator that is ideally suited for low power, low voltage applications in battery powered, low quiescent current, and a variety of other power systems.

The NCP4626DSN045T1G voltage regulator is ideal for providing power regulation in a variety of applications, such as mobile devices, wearables, and embedded systems. The low quiescent current and low dropout voltage make it the ideal choice for operating and charging batteries in low power systems.

The NCP4626DSN045T1G can provide power from a variety of input sources, such as Li-ion batteries, solar panels, and automobile standards. It also provides excellent regulation of the output voltage using an internal voltage reference, with a typical voltage derating of 0.1% per degree Celsius. The voltage regulator also features a low-noise regulator that can reduce power noise on any supply up to 250mV peak-to-peak.

The NCP4626DSN045T1G works on the basis of linear regulation; meaning that it takes a DC input voltage between the specified limits and provides a DC output voltage within the same range. The key components in the regulator are the voltage reference, error amplifier, pass transistor, and over-voltage protection circuit. It can operate in both normal and shutdown modes. In the normal mode, the pass transistor acts as a variable resistor, allowing a limited current to pass through. The current is then measured by the error amplifier and compared to the voltage reference. If the voltage reference differs from the output voltage, the error amplifier adjusts the pass transistor accordingly.

The NCP4626DSN045T1G also has an external overload protection circuit that acts as a fuse to prevent overcurrent damage. It also has reversed-polarity protection in case the input voltage source is wired incorrectly. The NCP4626DSN045T1G voltage regulator has a 5-pin SOT-23 package and comes with two output voltage options: 5.0V or 3.3V. It can also be configured for other output voltages from 0.8V to 5V.

Overall, the NCP4626DSN045T1G is a low power, low dropout linear voltage regulator that is ideal for low power applications such as those found in battery powered, low quiescent current, and other power systems. It has a wide input voltage range, low noise regulator, and over-voltage and reversed polarity protection. It provides excellent regulation of the output voltage and its 5-pin SOT-23 package makes it easy to use and install.
