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 3.0V 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 = (VIN – 3.0V) 150mA

315mW = VIN × 150mA – 450mW

810mW = VIN × 150mA

VIN(max) = 5.4V

Therefore, a 3.0V application at 150mA of output current

can accept a maximum input voltage of 5.4V in a SOT-

23-5 package. For a full discussion of heat sinking and

thermal effects on voltage regulators, refer to the “Reg-

ulator Thermals

” section of Micrel’s Designing with Low-

Dropout Voltage Regulators handbook.
