AME8820
High PSRR, CSP, 150mA CMOS LDO
As protection from damage due to excessive junc-
tion temperatures, the AME8820 has internal protec-
tion circuit. When junction temperature reaches ap-
proximately 150oC, the output device is turned off. Once
the device has cooled down to below approximately
125oC, regulator operation resumes.
For reliable operation,design is for worst case junc-
tion temperature of < 125oC taking into account worst
case ambient temperature and load conditions. De-
pending on each package type, presenting different
power dissipation, thermal resistance, and ambient
temperature, the thermal protection circuit may cycle
on and off. This cycling limits the dissipation of the
regulator, protecting it from damage due to overheat-
ing.
Any tendency to activate the thermal protection cir-
cuit indicates excessive power dissipation or inad-
equate heatsink. For reliable operation, junction tem-
perature should be limited to +125oC maximum. To
estimate the margin of safety in a complete Power
design (including heatsink), increase the ambient tem-
perature until the thermal protection is triggered; use
worst-case loads and signal conditions. For good reli-
ability, thermal protection should trigger at least +35oC
above the maximum expected ambient condition of
your particular application. This configuration produces
a worst-case junction temperature of +125oC at the
highest expected ambient temperature and worst-case
load. The internal protection circuitry of the AME8820
has designed to protect against overload conditions.
It was not intended to replace proper heatsinking. Con-
tinuously running the AME8820 into Thermal protec-
tion disables the output when the thermal shutdown
will degrade device reliability.
