Unauthorized Photocopy and Duplication Prohibited. © 2018 MPS. All Rights Reserved. OPERATION The MPQ20056 is a low -dropout linear regulator that can supply up to 250mA current , which makes it suitable for very low voltage, low quiescent, low noise , and high PSRR applications, such as wireless LAN transceivers, notebook computers, smartphones, and other low-power electronics. The MPQ20056 uses an internal PMOS as the pass element and includes both thermal shutdown and an internal current-limiting 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. Shutdown The MPQ20056 can be switched ON or OFF by a logic input at the EN pin : Logic high turns the regulator on and logic low turns it off. Tie the EN pin to VIN if the application does not require the shutdown feature. Do not float the EN pin. Current Limit The MPQ20056 includes a current limit structure that monitors and controls the PMOS gate voltage to limit the guaranteed maximum output current to 0.4A. Thermal Protection Thermal protection turns off the PMOS when the junction temperature exceeds 150 °C, allowing the IC to coo l. When the IC’s junction temperature drops by 20 °C, the PMOS will turn on again. Thermal protection limits total power dissipation in the MPQ20056. For reliable operation, limit the junction temperature to a maximum of 125°C. Load-Transient Considerations The output response of the load-transient consists of a transient response and DC shift — the MPQ20056’s excellent load regulation effectively limits the DC shift . The output voltage transient depends on the output capacitor’s value and ESR . Increasing the capacitance and decreasing the ESR will improve the transient response.

APPLICATION INFORMATION
Setting the Output Voltage The output voltage of the MPQ20056 is preset to 1.8V, 2.5V or 3.3V by intern al resistor divider. The output voltage also can be adjusted by using an external resistor divider (R1 and R2 in Figure 3). MPQ20056 VOUT FB GND Figure 3: Setting the Output Voltage However, the sum of R1 and R2 should not exceed 10kΩ to minimize their impact on the internal resistor divider. For an accurate output- voltage setting, use 1kΩ (±1%) for R2, and determine R1 with: FB FBOUT V VV2R1R For example, for a 1.1V output voltage, R2 is 1kΩ, and R1 is 374Ω. You can select a standard 374Ω (±1%) resistor for R1. Power Dissipation The power dissipation for any package depends on the thermal resistance of the case and circuit board, the temperature differential between the junction and ambient air, and the rate of air flow. The power dissipation across the device can be represented by the equation: The allowable power dissipation can be calculated using the following equation: JAAmbientJunction(M AX) TTP / Where (T Junction − T Ambient) is the temperature differential between the junction and the surrounding environment, θ JA is the thermal resistance from the junction to the ambient environment. Connecting the exposed GND pad to a large ground pad or plane helps to channel away heat. Output Capacitor Selection The MPQ20056 is specifically designed to work with a standard ceramic output capacitor to save space and improve performance. Use a 4.7µ F ceramic capacitor for most applications. Larger output capacitors will improve load transient response and reduc e noise at the cost of increased size.
