LP2982IM5X-5.0/NOPB

LP2982IM5X-5.0/NOPB is a multi-functional,linear low-dropout (LDO) voltage regulator from Texas instruments with output voltage of 5V and up to 500mA of output current. It is designed to deliver high performance and accuracy in a lightweight and compact form. With its wide range of features, it is suitable for any application where reliable independent supply is required.

The main features of LP2982IM5X-5.0/NOPB include: high-accuracy (±1.5%), low dropout voltage (50mV at 500mA), load transient protection, reverse-battery protection, thermal protection, and wide input voltage range (2.7V to 10.5V). It also supports external enable/shutdown control and output tracking. The LP2982IM5X-5.0/NOPB has a low power consumption of 1µA max at no load and an improved voltage transient rejection of 10dB at 10Hz.

LP2982IM5X-5.0/NOPB has a wide range of applications, such as cellular-phone subsystems, portable computing, industrial monitoring, medical systems, memory modules, embedded controllers, security systems, and many other applications that require a reliable, low-power voltage source. Its low power consumption and wide input voltage range make it suitable for battery applications.

LP2982IM5X-5.0/NOPB works on the principle of controlling the amount of driver current based on the required output voltage and the voltage across an error amplifier. The driver current flows through an internal foler resistance Rf, which is set by the output voltage. The output voltage is set by the internal reference voltage and a resistive divider network. The error amplifier compares the output voltage with a reference voltage and adjusts the difference till it is nearly zero, ensuring high accuracy even at high load. The thermal protection automatically shuts down the circuit if the output voltage exceeds the maximum specified temperature.

LP2982IM5X-5.0/NOPB is a very versatile, low-power and cost-effective solution for portable and mobile applications requiring a reliable and high-accuracy voltage source. It is also suitable for a wide range of other applications where a low-cost, low-power and high-accuracy voltage regulator is needed.
