LP2980IM5-3.2/NOPB

LP2980IM5-3.2/NOPB is a linear voltage regulator manufactured by Texas Instruments, with a wide range of applications. It offers excellent thermal performance, making it ideal for high-power applications, especially in noise sensitive applications.

LP2980IM5-3.2/NOPB is a low-noise, low-dropout linear voltage regulator designed to provide a regulated voltage output of 5.2V in a very small board space. It features on-chip thermal shutdown and reverse current protection, and low noise both during dropout and in normal operation. It is capable of delivering up to 150mA of output current with only 10µA of typical quiescent current.

LP2980IM5-3.2/NOPB is suitable for applications with high-current demands, such as powering microcontrollers, memory, LCDs, audio amplifiers, RF power amplifiers, and other components.

The LP2980IM5-3.2/NOPB’s output voltage can be easily adjusted using two external resistors. It is also capable of regulating diverse input voltages between 4.5V and 22V. It is available in an 8-pin package, making it suitable for small board space.

The working principle of the LP2980IM5-3.2/NOPB is based on the conventional voltage-regulator circuit. Its output voltage is determined by the ratio of two external resistors, R1 and R2. The output voltage is equal to (1 + (R2/R1)) x Vin. The output voltage is then compared with the internal reference voltage and is controlled by the internal error amplifier, which adjusts a PMOS pass transistor to regulate the output voltage.

The LP2980IM5-3.2/NOPB also features on-chip protection features including thermal shutdown, reverse-current protection and current-limiting protection. The thermal shutdown feature automatically turns off the regulator when the die temperature exceeds the specified limit, protecting the device from over-temperature damage. The reverse-current protection feature ensures that the current passing through the regulator does not exceed the specified limit, preventing the device from causing damage to the underlying components. The current-limiting protection feature helps to limit the current consumed by the regulator and protect the output from short-circuit and overload conditions.

In conclusion, the LP2980IM5-3.2/NOPB is a linear voltage regulator from Texas Instruments, with excellent thermal performance and on-chip protection features. It is suitable for powering microcontrollers, memory, LCDs, audio amplifiers, RF power amplifiers and other components. Its output voltage can be easily adjusted using two external resistors, and it can provide a regulated voltage output of 5.2V in a very small board space.
