MP20042 power management Series
Dual low-noise, high PSRR 200mA linear voltage regulators
The MP20042 power management series from Monolithic Power Systems is a pair of low-noise, high PSRR (power supply rejection ratio) linear voltage regulators, each capable of delivering up to 200mA of current. These regulators are designed for applications where noise and stability are critical, such as in audio equipment, precision instrumentation, and sensitive analog circuits.
If you're working on projects that require precise voltage regulation without the ripple and noise that can be introduced by switching regulators, these devices are a great choice. The high PSRR means they can effectively reject changes in the input voltage, providing a stable output even when the power supply fluctuates. This is particularly useful in environments where the power supply might be noisy or subject to frequent voltage drops.
One thing worth noting is their dual configuration, which allows for flexibility in design. You can use them in parallel to increase the current capability if needed, or simply as two independent regulators. Engineers tend to reach for this when they need a reliable, low-noise solution for power regulation in their designs. The MP20042 series is also known for its compact footprint, making it easy to integrate into space-constrained applications without compromising performance.
