DESCRIPTION
The MP2004 is a dual-channel, low noise, low dropout and high PSRR linear regulator. The output voltage of MP2004 ranges from 1.2V to 5V and 1% accuracy by operating from a +2.5V to +6.0V input. The MP2004 can supply up to 200mA of load current at each channel. The MP2004 uses an internal PMOS as the pass element, which consumes 114 μA supply current (both LDOs on) at no load condition. The EN1 and EN2 pins control each output respectively. When both channels shutdown simultaneously, the chip will be turned off and consume nearly zero operation current which is suitable for battery-power devices. The MP2004 features current limiting and over temperature protection. It is available in a small 6-pin TSOT23 package.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)- TA)/ θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside its operating conditions. 4) Measured on JESD51-7 4-layer board.

Unaut horized Photocopy and Duplication Prohibited. © 2010 MPS. All Rights Reserved. BLOCK DIAGRAM Figure1—Functional Block Diagram OPERATION The MP2004 integrates two low noise, low dropout, low quiescent current and high PSRR linear regulators. It is intended for use in devices that require very low voltage, low quiescent current power such as wireless LAN, battery- powered equipment and hand-held equipment. The MP2004 uses internal PMOSs as the pass elements and features internal thermal shutdown and an internal current limit circuit. 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. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage of MP2004 is very low. Shutdown The MP2004 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 The MP2004 includes two independent current limit structures which monitor and control each PMOS’s gate voltage limiting the guaranteed maximum output current to 200mA. Thermal Protection Thermal protection turns off the PMOS when the junction temperature exceeds +140ºC, allowing the IC to cool. When the IC’s junction temperature drops by 10ºC, the PMOS will be turned on again. Thermal protection limits total power dissipation in the MP2004. For reliable operation, junction temperature should be limited to 125 ºC maximum. Load-Transient Considerations The output response of load-transient consists of a DC shift and transient response. Because of the excellent load regulation of MP2004, the DC shift is very small. The output voltage transient depends on the output capacitor’s value and the ESR. Increasing the capacitance and decreasing the ESR will improve the transient response. Typical output voltage transient spike of MP2004 for a step change in the load current from 0mA to 80mA is tens mV.

PCB Layout Guide PCB layout is very important to achieve good regulation, ripple rejection, transient response and thermal performance. It is highly recommended to duplicate EVB layout for optimum performance. If change is necessary, please follow these guidelines and take Figure 5 for reference. 1) Input and output bypass ceramic capacitors are suggested to be put close to the IN Pin and OUT Pin respectively. 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.
