MP6401 300mA LDO Linear Regulator with Integrated Reset Circuit The Future of Analog IC Technology DESCRIPTION FEATURES The MP6401 combines a low-dropout linear regulator with an integrated reset circuit. It operates from a 2.5V to 5.5V input voltage and regulates the output voltage with 2% accuracy at 1.8V, 2.5V, 3.3V or adjustable value. It delivers up to 300mA of load current. By combining an LDO linear regulator with a reset circuit, these products can reduce cost and save space in compact portable devices such as cell phones, smart phones, PDAs, PMPs, and portable GPS devices. The MP6401 provides a push-pull, active-low that asserts when the regulator output voltage drops below the microprocessor supply threshold (-7.5% or -12.5% of nominal output voltage). Four reset delay time, 3.125ms, 25ms, 200ms and 1580ms can be selected. The MP6401 is available in 3mmx3mm TQFN8, 2mmx2mm TQFN6 and TSOT packages and is specified for operation from -40°C to 85°C. • • • • • • • • • • Low Quiescent Current of 80μA for Battery Powered Equipment Low 114mV Dropout at 300mA Output ±2％ Accurate Output Voltage Fixed Output Voltage Options of 1.8V, 2.5V or 3.3V Adjustable Output Voltage from 1.229V to 5V Using an External Resistor Divider 15μVRMS Ultra Low Noise Output PSRR: 57dB at 1kHz Input Reverse Current, Thermal and Short-Circuit Protection Microprocessor Reset with Four Delay time Options Push-Pull RESET APPLICATIONS • • • • Smart Phone and Cell Phone Portable GPS Devices Wireless Devices PDA and PMP All MPS parts are lead-free and adhere to the RoHS directive.

All Rights Reserved. 10 MP6401 – 300mA LDO LINEAR REGULATOR WITH INTEGRATED RESET IC OPERATION The MP6401 integrates a low noise, low dropout, low quiescent current linear regulator and a microprocessor reset circuit. It operates from a 2.5V to 5.5V input voltage and regulates the fixed output voltage with 2% accuracy at 1.8V, 2.5V, 3.3V or adjustable value. The MP6401 can supply to 300mA of load current. The internal reset circuit is used to monitor the regulator output voltage. The RESET asserts when the regulator output voltage drops below the standard microprocessor supply threshold. Linear Regulator The MP6401 can output a fixed voltage (1.8V, 2.5V, 3.3V options) or adjustable voltage which ranges from 1.25V to 5V with 2.0% accuracy by operating from a +2.5V to +5.5V input. The MP6401 can supply up to 300mA of load current. When ADJ is connected to GND, a fixed output voltage is selected. Connecting ADJ pin to the tap of external resistor divider from the OUT to GND, adjustable output voltage is selected. The typical ADJ connection is shown in Fig 3. 2.5V to 5.5V IN OUT MP6401 R1 ADJ EN GND R2 Figure 3—Output Voltage Adjusted with Resistor Divider Reset Function The reset circuit monitors the OUT voltage. RESET asserts while OUT voltage falls below its threshold. Two OUT voltage thresholds (-7.5% and -12.5%) are available. The power-up, power-down, and brownout conditions will make RESET asserted. So MP6401 monitor circuit could right control the microprocessor. RESET asserts when the input and output voltage below their thresholds. RESET asserts when EN is a low logic. When the assert trigger condition is removed, RESET will deassert after a fixed delay time. Four options of reset delay-time (see Table 3) can be selected. MP6401 Rev. 1.0 9/7/2012 EN Shutdown The MP6401 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 and the supply current is reduced. Generally, the EN pin should be tied to IN to keep the regulator output always on. Do not float the EN pin. Reverse Leakage Protection An internal circuit monitors VIN and VOUT to control the reverse leakage current from OUT to IN. While VIN decreases lower than VOUT and EN still hold logic high, the monitor circuit turns off the pass element and its parasitic diode. Typically the reverse leakage current through pass element decreases to 0.1uA. RESET deasserts until VIN returns greater than VOUT and VOUT is higher than its preset threshold. MP6401 also can work with backup battery at OUT after input power supply is removed as shown in Fig 4. When input power supply is removed, RESET asserts. The backup battery will power the device through two external diodes and typically the current from OUT to ground is 40uA. So, the power supply removing does not erase RAM content if the voltage of backup battery is greater than memory’s standby specification. The backup battery can be replaced by a super-cap, while the diode connected with battery is changed to a current-limiting resistor. Removable IN OUT MP6401 EN 3.3uF Backup Battery uP MEMORY Figure 4— Maintain Memory with Backup Battery Current Limit The MP6401 includes a current limit structure which monitors and controls pass element gate voltage limiting the guaranteed maximum output current to 500mA. www.MonolithicPower.com MPS Proprietary Information.

All Rights Reserved. 11 MP6401 – 300mA LDO LINEAR REGULATOR WITH INTEGRATED RESET IC Thermal Shutdown Thermal protection turns off the pass element when the junction temperature exceeds +150ºC, allowing to cool the IC. When the IC’s junction temperature drops by 20ºC, the pass element will be turned on again. Thermal protection limits total power dissipation on the MP6401. For reliable operation, junction temperature should be limited to 125 ºC maximum. MP6401 Rev. 1.0 9/7/2012 www.MonolithicPower.com MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2012 MPS. All Rights Reserved. 12 MP6401 – 300mA LDO LINEAR REGULATOR WITH INTEGRATED RESET IC APPLICATION INFORMATION Adjustable Regulator Output The OUT voltage of MP6401 has two modes available (fixed and adjustable output voltage). When ADJ pin is connected to GND, the regulator works in fixed voltage mode. The regulator output voltage will equal to preset voltage (1.8V, 2.5V or 3.3V options). In fixed voltage mode, the impedance between ADJ and ground should always be less than 50kΩ. Generally, ADJ is connected directly to ground. When the ADJ pin is connected to the tap of an external resistor divider, the regulator works in adjustable voltage mode as shown in Fig 3. The output voltage is selected by resistor divider, thus R + R2 VOUT = 1.229 × 1 R2 In adjustable voltage mode, R2 equal to 13kΩ is recommended as a good tradeoff among stability, accuracy and high-frequency PSRR. R2 should be not greater than 100kΩ. Output Capacitor Selection The MP6401 is designed specifically to work with very low ESR ceramic output capacitor 3.3uF (min). For performance consideration, a large ceramic capacitor such as 10uF is better. X7R or X5R capacitor dielectric is recommended. OUT Voltage Transient Immunity The MP6401 can be immune to OUT pin short negative transient. Typically, the immune duration is 60us with 10mV overdriving. A shorter negative transient can not make the RESET output assert. 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: be PD (MAX) = (TJ (MAX)-TA)/θJA Where (TJ(MAX)-TA) is the temperature difference between the junction and the ambient environment, θJA is the thermal resistance from the junction to the ambient environment. Connecting the GND pin of MP6401 to ground using a large pad or ground plane helps to channel heat away. MP6401 Rev. 1.0 9/7/2012 www.MonolithicPower.com MPS Proprietary Information.
