The total power dissipation of the device under these
conditions is the sum of the two power dissipation
figures.
PD(total) = PD × 50mA + PD × 500mA
PD(total) = 151mW + 119mW
PD(total) = 270mW
The total power dissipation of the regulator is less than
the maximum power dissipation of the SOT-23-5
package at room temperature, on a minimum footprint
board and therefore would operate properly.
Multilayer boards with a ground plane, wide traces near
the pads, and large supply-bus lines will have better
thermal conductivity.
For additional heat sink characteristics, please refer to
Micrel Application Hint 17, “Designing P.C. Board Heat
Sinks”, included in Micrel’s Databook. For a full
discussion of heat sinking and thermal effects on voltage
regulators, refer to Regulator Thermals section of
Micrel’s Designing with Low-Dropout Voltage Regulators
handbook.

Figure 5. Low-Noise Fixed Voltage Regulator
Figure 5 shows a basic MIC5216-x.xBMx fixed-voltage
regulator circuit. A 1F minimum output capacitor is
required for basic fixed-voltage applications.
The flag output is an open-collector output and requires
a pull-up resistor to the input voltage. The flag indicates
an undervoltage condition on the output of the device.
