CMPWR150

Typical Thermal Characteristics (continued)

The CMPWR150TO therefore requires no additional heat

sinking. All thermal characteristics were measured with the

TO-263 package using minimum size solder pads and tab.

Measurements showing performance up to maximum

junction temperature of 125°C were performed under light

load conditions (5mA). This allows the ambient

temperature to be representative of the internal junction

temperature.

Output Voltage vs. Temperature. Figure 12 shows

the regulator VOUT performance up to the maximum rated

junction temperature. The overall 100°C variation in

junction temperature causes an output voltage change of

about 30mV, reflecting a voltage temperature coefficient

of 90ppm/°C.

Figure 13. Output Voltage (500mA) vs. Temperature.

Thresholds vs. Temperature. Figure 14 shows the

regulator select/deselect threshold variation up to the

maximum rated junction temperature. The overall 100°C

change in junction temperature causes a 30mV variation

in the select threshold voltage (regulator enable). The

deselect threshold level varies about 50mV over the 100°C

change in junction temperature. This results in the built-

in hysteresis having minimal variation over the entire

operating junction temperature range.

Output Voltage (500mA) vs. Temperature. Figure 13

shows the regulator steady state performance when fully

loaded (500mA) in an ambient temperature up to the rated

maximum of 70°C. The output variation at maximum load is

approximately 25mV across the normal temperature range.
