The junction-to-ambient thermal resistance for the
minimum footprint is 235°C/W, from Table 1. The
maximum power dissipation must not be exceeded for
proper operation. Using the output voltage of 1.2V and
an output current of 150mA, the maximum input voltage
can be determined. Because this device is CMOS and
the ground current is typically 100μA over the load
range, the power dissipation contributed by the ground
current is < 1% and can be ignored for this calculation.
315mW = (V IN – 1.2V) 150mA
315mW = V IN ·150mA – 195mW
510mW = V IN ·150mA
V IN (max) = 3.4V
MIC5268
Therefore, a 1.2V application at 150mA of output current
can accept a maximum input voltage of 3.4V in a SOT-
23-5 package. For a full discussion of heat sinking and
thermal effects on voltage regulators, refer to the
Regulator Thermals section of Micrel’s Designing with
Low-Dropout Voltage Regulators handbook.
Dual-Supply Operation
When used in dual supply systems where the regulator
load is returned to a negative supply, the output voltage
must be diode clamped to ground.
