Line Step Response. Figure 11 shows the output response
V OUT offset = 3.3 V
of the regulator to a V CC line voltage transient between
4.5 V and 5.5 V (1 Vpp as shown on Ch1). The load
condition during this test is 5 mA. The output response
produces less than 10 mV of disturbance on both edges
indicating a line rejection of better than 40 dB at high
frequencies.

TYPICAL THERMAL CHARACTERISTICS
Thermal dissipation of junction heat consists primarily of
two paths in series. The first path is the junction to the case
( q JC ) thermal resistance, which is defined by the package
style, and the second path is the case to ambient ( q CA )
the rmal resistance, which is dependent on board layout.
For a given package style and board layout, the operating
junction temperature is a function of junction power
dissipation P JUNC and the ambient temperature, resulting in
the following thermal equation:
T JUNC + T AMB ) T JUNC ( q JC ) ) P JUNC ( q CA )
Measurements showing performance up to maximum
junction temperature of 125 ° C were performed under light
load conditions (5 mA). This allows the ambient
Output Voltage vs. Temperature. Figure 12 shows the
regulator V OUT performance up to the maximum rated
junction temperature. The overall 100 ° C variation in
junction temperature causes an output voltage change of
about 30 mV, reflecting a voltage temperature coefficient of
90 ppm/ ° C.
Output Voltage (500 mA) vs. Temperature. Figure 13
shows the regulator steady state performance when fully
loaded (500 mA) in an ambient temperature up to the rated
maximum of 70 ° C. The output variation at maximum load
is approximately 25 mV across the normal temperature
range.
temperature to be representative of the internal junction
temperature.
