Monolithic Power Systems, Inc. Integrated Circuits (ICs) - Power Management (PMIC) - Voltage Regulators - Linear MP2009EE-3.3-LF-P

The MP2009EE-3.3-LF-P is a low-dropout linear voltage regulator designed to provide a stable output voltage of 3.3V with a maximum output current of 120mA. It operates with an input voltage range of 2.0V to 6.0V and features a low dropout voltage of 120mV at full load. The device is optimized for low output noise, achieving 16µVRMS without the need for a bypass capacitor, making it suitable for noise-sensitive applications. It has a power supply rejection ratio (PSRR) of 78dB at 1kHz, ensuring minimal output voltage variation due to input fluctuations. The regulator is stable with a small output capacitance of just 1µF, which is beneficial for space-constrained designs. Additionally, it includes built-in current limit and thermal protection features to enhance reliability. The MP2009EE-3.3-LF-P is packaged in a compact 5-pin SC70 format, making it ideal for portable and battery-powered devices such as cellular phones, digital cameras, and wireless LANs.
