DESCRIPTION
The MP2009 is an ultra low noise, low dropout linear regulator. The output voltage of MP2009 ranges from 1.5V to 4.5V in 100mV increments and 1% accuracy by operating from a +2.0V to +6.0V input. It is designed to deliver up to 120mA continuous output current. It achieves a low 120mV dropout for full load current. The MP2009 uses an internal PMOS as the pass element, which consumes 50µA supply current at no load condition. New innovative design techniques make MP2009 achieve ultra- low output voltage noise of 16µV RMS without a noise bypass capacitor. The MP2009 are designed and optimized to work with low value, low cost ceramic capacitors in space-limiting and performance consideration. It requires only 1µF (typ) of output capacitance for stability with any load. It is available in a 5-pin SC70 package.

Unauthorized Photocopy and Duplication Prohibited. © 2013 MPS. All Rights Reserved. OPERATION The MP2009 is an ultra low noise, low dropout, low-quiescent current linear regulator designed for space-restricted applications. It is intended for use in devices that requires very low voltage, low quiescent current such as wireless LAN, battery- powered equipment and hand-held equipment. Internal P-Channel Pass Transistor The MP2009 features a 1.4 Ω P-channel MOSFET as the pass transistor. It provides several advantages over similar designs using PNP pass transistor. The P-channel MOSFET requires no base drive, which reduces quiescent current considerably and increase the battery life. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive current under the large load condition. The MP2009 does not suffer from these problems and consume only 50µA of quiescent current in light load and dropout mode. Dropout Voltage Dropout voltage is the minimum input to output differential voltage required for the regulator to maintain an output voltage within 100mV of its nominal value. It determines the available end-of- life battery voltage in battery-powered systems. For the P-channel MOSFET pass element, the dropout voltage is a function of drain to source on resistance. Because the P-channel MOSFET pass element behaves as a low-value resistor, the dropout voltage of MP2009 is very low. Shutdown The MP2009 can be switched ON or OFF by a logic input at the EN pin. A high voltage at this pin will turn the device on. When the EN pin is low, the regulator output is off. The EN pin should be tied to VIN to keep the regulator output always on if the application does not require the shutdown feature. Do not float the EN pin. Current Limit and Thermal Protection The MP2009 includes an independent current limit structure which monitors and controls the P- channel MOSFET’s gate voltage to limit the guaranteed maximum output current to 120mA. Thermal protection turns off the P-channel MOSFET when the junction temperature exceeds +150ºC, allowing the IC to cool. When the IC’s junction temperature drops by 20ºC, the PMOS will be turned on again. Thermal protection limits total power dissipation in the MP2009. For reliable operation, junction temperature should be limited to 125 ºC maximum.

APPLICATION INFORMATION
The power dissipation for any package depends on the thermal resistance of the case and circuit board, the temperature difference between the junction and ambient air, and the rate of airflow. The power dissipation across the device can be represented by the equation: P = (V IN - VOUT) ×IOUT The allowable power dissipation can be calculated using the following equation: P(MAX) = (TJunction - TAmbient) / θJA Where (T Junction - T Ambient) is the temperature difference between the junction and the surrounding environment, θJA is the thermal resistance from the junction to the ambient environment. Connecting the GND pin of MP2009 to ground with a large ground plane will help the channel heat away. Output Noise and PSRR For the MP2009, an internal 50pF bypass capacitor with new innovative structure reduces output noises greatly. It does not need external bypass capacitor for space-limiting applications. The power supply rejection is 75dB at 10kHz and 55dB at 100kHz. (See the PSRR vs. Frequency graph in the Typical Performance Characteristics). Input Capacitor Selection Use a 1µF capacitor on the input of the MP2009. Larger values will help to improve line transient response with the drawback of increased size . Ceramic capacitors are preferred, but tantalum capacitors may also suffice. Output Capacitor Selection The MP2009 is designed specifically to work with very low ESR ceramic output capacitor in space- limiting and performance consideration. Output capacitor of larger values will help to improve load transient response and reduce noise with the drawback of increased size. A 1µF ceramic capacitor with ESR lower than 3 Ω is sufficient for the MP2009 application circuit. (See the Region of Stable C OUT ESR vs. Load Current graph in the Typical Performance Characteristics)
