Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2019 MPS. All Rights Reserved. 11 MP20056 – LOW-NOISE, HIGH-PSRR, 250mA LINEAR REGULATOR OPERATION The MP20056 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 MP20056 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 MP20056 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 MP20056 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 cool. When the IC’s junction temperature drops by 20°C, the PMOS will turn on again. Thermal protection limits total power dissipation in the MP20056. 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 MP20056’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.

All Rights Reserved. 12 MP20056 – LOW-NOISE, HIGH-PSRR, 250mA LINEAR REGULATOR APPLICATION INFORMATION Setting the Output Voltage The output voltage of the MP20056 is preset to 1.8V, 2.5V or 3.3V by internal resistor divider. The output voltage also can be adjusted by using an external resistor divider (R1 and R2 in Figure 2). VOUT Output Capacitor Selection The MP20056 is specifically designed to work with a standard ceramic output capacitor to save space and improve performance. Use a 4.7µF ceramic capacitor for most applications. Larger output capacitors will improve load transient response and reduce noise at the cost of increased size. R1 MP20056 FB R2 GND Figure 2: 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 outputvoltage setting, use 1kΩ (±1%) for R2, and determine R1 with: V  VFB R1  R2   OUT VFB  Where (TJunction − TAmbient) is the temperature differential between the junction and the surrounding environment, θJA 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.    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: External Reverse Voltage Protection In some situations, e.g. a backup battery is connected as MP20056 load, the output voltage may be held up while the input is either pulled to ground to some intermediated voltage or is floating. Thus, the output voltage is higher than input voltage. Since MP20056 internal PMOS pass element has a body diode, a current will conduct from the output to input and is not internally limited. It’s possible that the IC will be damaged by this unlimited reverse current. To avoid this, it’s recommended to place an external diode at input like below.
