All Rights Reserved. 10 MP2009-ULTRA LOW NOISE, LOW DROPOUT,120mA LINEAR REGULATOR 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, batterypowered equipment and hand-held equipment. Internal P-Channel Pass Transistor The MP2009 features a 1.4Ω 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-oflife 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. MP2009 Rev. 1.2 12/18/2013 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 Pchannel 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. www.MonolithicPower.com MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2013 MPS. All Rights Reserved. 11 MP2009-ULTRA LOW NOISE, LOW DROPOUT,120mA LINEAR REGULATOR APPLICATION INFORMATION Power Dissipation 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 = (VIN - VOUT) ×IOUT The allowable power dissipation can calculated using the following equation: P(MAX) = (TJunction - TAmbient) / θJA be Where (TJunction - TAmbient) 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 MP2009 Rev. 1.2 12/18/2013 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 spacelimiting 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 3Ω is sufficient for the MP2009 application circuit.

It is highly recommended to duplicate EVB layout for optimum performance. 2) Ensure all feedback connections are short and direct. Place the feedback resistors and compensation components as close to the chip as possible. 3) Connect IN, OUT and especially GND respectively to a large copper area to cool the chip to improve thermal performance and long-term reliability. If change is necessary, please follow these guidelines and take figure 2 for reference. 1) Input and output bypass ceramic capacitors are suggested to be put close to the IN Pin and OUT Pin respectively.
