The LP3882ES-1.5/NOPB is a high performance, cost effective voltage regulator from Texas Instruments. This device is classified as one of the linear voltage regulators in the power management integrated circuit (PMIC) family.

The LP3882ES-1.5/NOPB is capable of delivering an output voltage range of 1.5 V to 28 V making it suitable for a wide variety of applications such as PC motherboard, digital televisions and set-top boxes and other consumer electronics, as well as industrial applications such as motor controllers and power supplies. The device can operate with a supply voltage of up to 40 V, making it ideal for high voltage, high current applications.

The LP3882ES-1.5/NOPB features a low drop out voltage (LDO) design. This allows for a low-voltage input with a high-current output, making it ideal for applications that require high accuracy and high power efficiency. The device also features an output short circuit current limit feature that prevents the device from being damaged by short circuit conditions.

The LP3882ES-1.5/NOPB also features programmable under-voltage lockout (UVLO), thermal shutdown (TSD), current limit (CL) and current monitoring (CM) functions for system protection. It also includes frequency foldback (FF) and remote sense pins for improved accuracy and performance.

The LP3882ES-1.5/NOPB employs a voltage regulation principle that allows the output voltage to remain stable even when there are changes in the load current or input voltage. This is achieved by a bandgap reference circuit and an error amplifier. The bandgap reference circuit generates a precise voltage reference that is used to compare against the input voltage and the error amplifier compares the output voltage with the voltage reference. The error amplifier then adjusts the output current to maintain the output voltage at the desired level.

The LP3882ES-1.5/NOPB can also provide up to 90% power efficiency while delivering efficiency improvements of up to 2.5 W without the need for external components. It also features a wide power supply rejection ratio (PSRR) of 55 dB, which helps to reduce ripple at the output. Finally, it offers an adjustable output current limit, enabling it to meet different application requirements.

The LP3882ES-1.5/NOPB is an ideal device for applications that require precise voltage regulation, low power consumption and high efficiency. With its wide range of features and support for a wide range of input voltages and output currents, it is a cost-effective solution for a variety of applications.
