The MP2016 has an output that is adjustable from 1.2V to 40V with a simple resistor divider. The maximum power output current is a function of the package’s maximum power dissipation for a given temperature. The MP2016 uses external feedback, allowing the user to set the output voltage with an external resistor divider. The typical FB pin threshold is 1.23V. The IC enters shutdown mode when SHDN is low. In shutdown mode, the pass transistor, control circuitry, reference and all biases turn off, reducing the supply current to <2µA. Connect SHDN to IN for automatic startup. MP2016 Rev.1.0 10/10/2011 The peak output current is limited to 50mA, which exceeds the 30mA recommended continuous output current. The output can be shorted to ground for 30 seconds without damaging the part. When the junction temperature is too high, the thermal sensor sends a signal to the control logic that will shutdown the IC. The IC will restart when the temperature has sufficiently cooleds. The maximum power dissipation is dependent on the thermal resistance of the case and the circuit board, the temperature difference between the die junction and the ambient air, and the rate of air flow. The GND pin and Exposed Pad must be connected to the ground plane for proper dissipation. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.

This noise is negligible for most applications. However, in applications that include analog-to-digital converters (ADCs) of more than 12 bits, one needs to consider the ADC’s power supply rejection specifications. The feed forward capacitor C3 across R1 will significantly reduce the output noise. MP2016 FB 4 2 Figure 2—MP2016 with External Resistor Divider Choose R2=250kΩ to maintain a 5µA minimum load. Calculate the value for R1 using the following equation: ⎛ V ⎞ R1 = R2 × ⎜ OUT − 1⎟ ⎝ 1.23V ⎠ Input Capacitor For proper operation, place a ceramic capacitor (C1) between 1µF and 10µF of dielectric type X5R or X7R between the input pin and ground. Larger values in this range will help improve line transient response. Output Capacitor For stable operation, use a ceramic capacitor (C2) of type X5R or X7R between 1µF and 10µF. Larger values in this range will help improve load transient response and reduce noise. Output capacitors of other dielectric types may be used, but are not recommended as their capacitance can deviate greatly from their rated value over temperature. To improve load transient response, add a small ceramic (X5R, X7R or Y5V dielectric) 22nF feed forward capacitor in parallel with R1. The feed forward capacitor is not required for stable operation.
