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-

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.

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:
