Working Principle:

LP3996SDX-3033/NOPB Linear voltage regulator is a three-terminal positive-voltage regulator that works on the principle of feedback control. It has a low input voltage of 4.5V and a maximum output voltage of 24V. The regulator is composed of two integrated stages: an input stage and an output stage. The input stage features a three-terminal regulator that is connected to the output stage by means of an output voltage-setting divider. This divider sets a reference voltage that is compared to the output voltage by an error amplifier. The output stage is designed to control the output current for a given load current by changing the PNP-base current and thus changing the output voltage of the internal reference voltage. The error amplifier provides feedback and corrects the output voltage to a predefined level. It features an adjustable voltage range that can be set by the user in order to get the optimal performance.

LP3996SDX-3033/NOPB Linear voltage regulator provides excellent load and line regulation and over-temperature protection. It is stable with small-signal capacitors, providing high power-supply rejection and excellent transient performance. The regulator is available in multiple packages for easy design integration. Its wide operating temperature range makes it suitable for automotive and industrial applications.

Conclusion:

LP3996SDX-3033/NOPB Linear voltage regulator is an ideal solution for high-current and high-voltage applications. It is a three-terminal positive-voltage regulator and provides up to 1.6A output current in a wide, adjustable output voltage range of up to 24V. Its wide operating temperature range makes it suitable for automotive and industrial applications. It is available in multiple packages for easy design integration.
