______________________________________________________________________________________
The GND pins of the MAX882/MAX883/MAX884 SOIC
package perform the dual function of providing an elect-
rical connection to ground and channeling heat away. Con-
nect all GND pins to ground using a large pad or ground
plane. Where this is impossible, place a copper plane on an
adjacent layer. For a given power dissipation, the pad
should exceed the associated dimensions in Figure 4.
Figure 4 assumes the IC is in an 8-pin small-outline pack-
age that has a maximum junction temperature of +125°C
and is soldered directly to the pad; it also has a +25°C
ambient air temperature and no other heat sources. Use
larger pad sizes for other packages, lower junction tem-
peratures, higher ambient temperatures, or conditions
where the IC is not soldered directly to the heat-sinking
ground pad. When operating C and E grade parts up to a
T
J
of +125°C, expect performance similar to M grade
specifications. For T
J
between +125°C and +150°C, the
output voltage may drift more.
The MAX882/MAX883/MAX884 can regulate currents up
to 250mA and operate with input voltages up to 11.5V, but
not simultaneously. High output currents can only be sus-
tained when input-output differential voltages are small, as
shown in Figure 5. Maximum power dissipation depends
on packaging, temperature, and air flow. The maximum
output current is as follows:
