NCV4299D233R2G

NCV4299D233R2G is a Linear Voltage Regulators product in PMIC (Power Management IC) family. It is a low dropout (LDO) voltage regulator that provides precise output voltage regulation, low noise, low power consumption, and fast transient response. This device is ideally suited for providing a regulated voltage to a variety of low-power applications such as battery-powered devices, high-efficiency DC-DC converters, high-accuracy DC-DC regulation, and other sensitive analog circuitry.

NCV4299D233R2G offers significant advantages for battery-powered applications. It supports an ultra-low quiescent current of only 300μA (typical), which allows for longer battery life in many applications. It also provides low output noise and fast transient response, which is beneficial in portable communications applications, such as voice/data communication.

NCV4299D233R2G has an input range of 1.8V to 5.5V, with ±2% accuracy and 0.1V resolution. Output voltage range is adjusted via external resistors, with the output voltage ranging from 1.24V to 6V. The part also features a wide array of built-in protection features, including under-voltage lockout, over-voltage protection, and overtemperature shutdown. Additionally, it is stable with many types of capacitive loads, including ceramic capacitors.

In addition to its superior performance characteristics, NCV4299D233R2G is available in a variety of packages, including a small 8-pin VSSOP (3mm x 3mm) for high-density applications. The packages also incorporate E-pad technology, which allows for improved thermal and electrical performance of the device.

The working principle of NCV4299D233R2G is based on its Linear Voltage Regulation capabilities. It works by actively controlling the voltage across its output, thus allowing it to automatically correct voltage errors and deliver a steady output. This is achieved by use of an internal reference (typically 1.2V) and a control loop. The output voltage is set by comparing the feedback voltage to the reference voltage, and comparator then adjusts the output to match the reference. The feedback voltage is taken directly from the output port. The internal control loop then adjusts the output voltage in an effort to maintain the voltage output in compliance with the internal reference.
