LP2975IMM-12/NOPB

LP2975IMM-12/NOPB is a low-noise, low-drop out (LDO) voltage regulator controller designed for mobile and other battery-powered systems. This integrated circuit can deliver up to 2 amps of output current to loads whose power consumption requirements range from few milliamps at very low voltages to 1 A at its maximum output voltage level of 5.5V. The LP2975IMM-12/NOPB features an on-chip 200 mV reference voltage, a feedback voltage monitoring system and programmable current limit, making the device well suited for the increasingly demanding applications of smartphones, tablets and other portable electronic devices.

LP2975IMM-12/NOPB\'s application field is focused on delivering clean and stable power to complex systems, supplying voltage to components like CPUs, GPUs and memory, while controlling the output voltage within a tight tolerance range. This ensures that every component gets the precise amount of power it needs from the power supply, limiting power dissipation and improving overall efficiency.

It is suitable for an extensive range of battery-powered applications, thanks to the low operating power dissipation—typically less than 0.1 mW—and a wide input voltage range of 2V to 7V. It\'s ideal for applications like point-of-load regulation, portable electronic device power supply and system power management in automotive, avionics and industrial systems. The combination of low-noise and high accuracy makes the LP2975IMM-12/NOPB the perfect choice for applications that require a very stable and clean output voltage.

The LP2975IMM-12/NOPB consists of a voltage reference, an error amplifier, a driver circuit, an over-current protection circuit and a power MOSFET. The voltage reference ensures that the output voltage is held stable, while the error amplifier and driver circuit monitor the output voltage and provide feedback for the voltage control loop. The integrated MOSFET serves as a switch that can be closed and opened by the controller, to regulate the current between the input and output of the system. The over-current protection circuit ensures the safety of the device, by monitoring the output current and activating the over-current protection circuit if the current exceeds a certain point.

In addition, the LP2975IMM-12/NOPB also features low-noise operation and a low drop-out voltage of 130 mV, allowing it to supply power to the load over a wide input voltage range with minimal drop-out voltage. This makes it suitable for applications with low noise and power requirements. The device also has a very small footprint, which makes it easy to incorporate into boards with minimal space limitations.

Overall, the LP2975IMM-12/NOPB is a highly reliable and efficient LDO low-noise voltage regulator controller that can be used in a variety of applications where low drop-out voltage, low power dissipation, and good voltage regulation are required. This device is ideal for providing stable and clean power to highly demanding systems and is well suited for embedded systems and smartphone designs.
