Monolithic Power Systems, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MP2009EE-2.5-LF-P

The MP2009EE-2.5-LF-P is a low-dropout linear voltage regulator designed to provide a stable output voltage of 2.5V 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 140mV at full load. The device exhibits ultra-low output noise of 16µVRMS, eliminating the need for a bypass capacitor, which simplifies the design. It is stable with a minimal output capacitance of just 1µF, making it suitable for space-constrained applications. The regulator has a power supply rejection ratio (PSRR) of 78dB at 1kHz, ensuring effective noise filtering. It consumes a low ground current of 50µA under no-load conditions and includes built-in current limit and thermal protection features to safeguard against overload conditions. The MP2009EE-2.5-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.
