3. Current limit protection
n Application Description
AME1084 is protected against overload conditions.
Current protection is triggered at typical 7.5A.
1. Output voltage adjustment
Like most regulators, the AME1084 regulates
the output by comparing the output voltage to
an internally generated reference voltage. On
the adjustable version, the VREF is available ex-
ternally as 1.25V between VOUT and ADJ. The
voltage ratio formed by R1 and R2 should be
set to conduct 10mA (minimum output load).
The output voltage is given by the following
equation:
4. Stability and load regulation
AME1084 requires a capacitor from VOUT to GND t o
provide compensation feedback to the internal gain
stage. This is to ensure stability at the output termi-
nal. Typically, a 10µF tantalum or 50µF aluminum
electrolytic is sufficient.
Note: It is important that the ESR for this capacitor
does not exceed 0.5Ω.
R2
VOUT = VREF ( 1 +
) + IADJ x R2
R1
The output capacitor dose not have a theoretical
upper limit and increasing its value will increase
stability. COUT = 100µF or more is typical for high cur-
rent regulator design.
On fixed versions of AME1084, the voltage di-
vider is provided internally.
For the adjustable version, the best load regulation is
accomplished when the top of theresistor divider
(R1) is connected directly to theoutput pin of the
AME1084. When so connected, RP is not multiplied
by the divider ratio.

2. Thermal protection

AME1084 has thermal protection which limits
junction temperature to 150OC. However, de-
vice functionality is only guaranteed to a maxi-
mum junction temperature of +125OC.

5. Thermal consideration
The AME1084 series contain thermal limiting
circuitry designed to protect itself for over-
temperature conditions. Even for normal load
conditions, maximum junction temperature
ratings must not be exceed. As mention in
thermal protection section, we need to con-
sider all sources of thermal resistance be-
tween junction and ambient. It includes junc-
tion-to-case, case-to-heat-sink interface and
heat sink thermal resistance itself.
Junction-to-case thermal resistance is speci-
fied from the IC junction to the bottom of the
case directly below the die. Proper mounting
is required to ensure the best possible ther-
mal flow from this area of the package to the
heat sink. The case of all devices in this se-
ries is electrically connected to the output.
Therefore, if the case of the device must be
electrically isolated, a thermally conductive
spacer is recommended.
