Key Featrues

Ultra-Low Output Noise (11µVRMS): The MAX8840 achieves an ultra-low output noise of 11µVRMS within a 100Hz to 100kHz bandwidth, making it ideal for sensitive applications like audio equipment, wireless communication devices, and precision instrumentation. This feature ensures high signal integrity and reduces interference in noise-critical systems.
High Power Supply Rejection Ratio (78dB at 1kHz): With a PSRR of 78dB at 1kHz, the MAX8840 effectively filters out power supply noise, enhancing the stability and performance of devices in environments with fluctuating or noisy power sources. This is particularly beneficial for battery-powered and RF applications.
Low Dropout Voltage (120mV at 120mA): The regulator maintains a low dropout voltage of 120mV at 120mA load, enabling efficient operation even with low input voltages. This feature extends battery life in portable devices and ensures reliable performance in low-power scenarios.
Compact µDFN Package (1.0mm x 1.5mm x 0.8mm): The space-saving µDFN package allows for integration into compact and densely populated PCBs, making it suitable for small form-factor devices such as wearables, IoT modules, and mobile accessories.
Stable with 1µF Ceramic Capacitor: The MAX8840 remains stable with just a 1µF ceramic capacitor, reducing the need for additional external components. This simplifies design, lowers BOM costs, and saves board space, making it an efficient choice for streamlined electronic designs.
