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 approximately 1” square of 1 oz copper. www.MonolithicPower.com MPS Proprietary Information.

In addition, RBIAS needs to be large enough that the quiescent current does not exceed 10mA when the supply voltage is at its maximum and the load current is at its minimum. Choose RBIAS using the following equation: R BIAS = VSUPPLY − VOUT IL + I Q Adjustable Precision Voltage Source The MP8200 can be combined with a precision op amp to produce a precise adjustable output voltage. See Figure 1. The output of the op amp is determined by the gain of the circuit using the following equation: VOUT = 1 + R1 R2 VCC T O RBIAS VOUT MP8200 Figure 2—Output Voltage Trim Precise Negative Voltage Reference The MP8200 can be configured for use in applications where a precise negative voltage reference is needed. + MP8200 - -1.0V -VDD Figure 3—Precise –1.0V Reference Choose R1 such that 100µA to 10mA is provided to properly bias the MP8200, using the equation: RBIAS 1.0V VCC R1 An optional capacitor can be added in parallel with R2 to filter out high frequency noise. N Output Voltage Trim Using a mechanical or digital potentiometer, the output voltage of the MP8200 can be trimmed to ±0.5%. See Figure 2. Note that trimming other resistor values may not produce an accurate output from the MP8200. R EC R NE O EF W M ER D ME E N TO SI D ED G M N P8 S FO 20 R 1 External Bias Resistor In the case of shunt voltage references, an external bias resistor (RBIAS) is required between the supply voltage and the MP8200. RBIAS sets the current that is required to pass through the load and the IC. + MP8200 VOUT -- R1 = VDD I MP8200 R1 R2 C2 (Opt.)
