MP20043 Dual Channel, 300mA Linear Regulator With Programmable Output Voltage and Output Discharge The Future of Analog IC Technology DESCRIPTION FEATURES The MP20043 is a dual-channel, low noise, low dropout and high PSRR linear regulator with programmable output voltage. The output voltage of MP20043 ranges from 1.2V to 3.3V in 100mV increments and 2.5% accuracy by operating from a +2.5V to +5.5V input. The different output voltage options can be programmed by setting the voltage of P1 and P2 to VDD, GND or floating. There are 9 different voltage settings in one chip. Each output channel can supply up to 300mA of load current. The MP20043 uses two internal PMOSs as the pass devices, which consumes 150μA supply current when both channels are enabled at no load condition. The EN1 and EN2 pins control each output respectively. When both channels shutdown simultaneously, the chip turns off and consumes nearly zero operation current which is suitable for battery-power devices. The MP20043 also features current limiting and over temperature protection. It is available in a TQFN8 (2mm×2mm) package Programmable Output Voltage Up to 300mA Output Current (Each LDO) 60mV Dropout at 100mA Load Dual Shutdown Pins Control Each Output 75dB PSRR at 1kHz 7μVRMS Low Noise Output Current Limiting and Thermal Protection Short Circuit Protection Two LDOs in TQFN8 (2mm×2mm) Package Output Load Discharge when Disabled APPLICATIONS Cellular Phones Battery-powered Equipment Laptop, Notebook, and Palmtop Computers Hand-held Equipment Wireless LAN All MPS parts are lead-free and adhere to the RoHS directive.

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 of its operating conditions. 4) Measured on JESD51-7 4-layer board. www.MonolithicPower.com MPS Proprietary Information.

Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2013 MPS. All Rights Reserved. 10 MP20043 –DUAL-CHANNEL, 300mA LDO WITH PROGRAMMABLE OUTPUT VOLTAGE OPERATION The MP20043 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. Output voltages are optional ranging from 1.2V to 3.3V, and each channel can supply current up to 300mA. The part uses internal PMOSs as the pass elements and features internal thermal shutdown and internal current limit circuits. 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 MP20043 is very low. Shutdown The MP20043 has two EN pins to control each channel respectively. And each channel 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 MP20043 Rev.1.0 1/14/2013 tied to VIN to keep the regulator output always on if the application does not require the shutdown feature. Do not float the EN pins. Current Limit The MP20043 includes two independent current limit structures which monitor and control each PMOS’s gate voltage limiting the guaranteed maximum output current to 490mA. 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 MP20043. For reliable operation, the junction temperature should be limited to 125 ºC maximum. Internal P-Channel Pass Device The MP20043 features dual typical 0.6Ω Pchannel MOSFET pass devices. It provides several advantages over similar designs using PNP pass transistors, including longer battery life. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.

All Rights Reserved. 11 MP20043 –DUAL-CHANNEL, 300mA LDO WITH PROGRAMMABLE OUTPUT VOLTAGE APPLICATION INFORMATION Output Voltage The output voltage of MP20043 is programmable with setting different states of P1 PIN and P2 PIN. For combination A, the setting rule is as the following table: Output Capacitor Selection The MP20043 is designed specifically to work with very low ESR ceramic output capacitor in space-saving and performance consideration. A ceramic capacitor in the range of 0.47µF and 10µF, and with ESR lower than 1Ω is suitable for the MP20043 application circuit. Output capacitor of larger values will help to improve load transient response and reduce noise with the drawback of increased size. Table 1 Programmable Output Voltage Setting (Combination A) P1 State L L L H H H Open Open Open P2 State L H Open L H Open L H Open VOUT1 1.5V 1.8V 1.8V 1.8V 1.8V 2.7V 2.8V 2.9V 2.8V Input capacitor of larger value will help improve line transient response with the drawback of increased size. Ceramic capacitors are preferred, but tantalum capacitors may also sufficient. VOUT2 2.8V 2.9V 2.8V 2.7V 2.6V 2.8V 2.8V 2.9V 3.3V . For example, when P1 and P2 are both open, output voltage of channel 1 is 2.8V, and the output voltage of channel 2 is 3.3V. 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. Connect the GND pin of MP20043 to ground using a large pad or ground plane helps to channel heat away. Input Capacitor Selection Using a capacitor whose value is >0.47µF on the MP20043 input and the amount of capacitance can be increased without limit.
