Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (T
J
) within the
operating temperature range, unless otherwise noted. 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.
(V
IN
- V
OUT
) is limited to keep the product (I
OUT
x (V
IN
- V
OUT
)) from exceeding the package power dissipation limits. See
Figure 5. Therefore, the combination of high output current and high supply voltage is not tested. Output current at
T
J
= +125°C is guaranteed by guard banding tests at T
J
= +85°C and +70°C.
Dropout Voltage is (V
IN
- V
OUT
) when V
OUT
falls to 100mV below its nominal value at V
IN
= (V
OUT
+ 2V). For example, the
MAX883 is tested by measuring the V
OUT
at V
IN
= 7V, then V
IN
is lowered until V
OUT
falls 100mV below the measured
value. The difference (V
IN
- V
OUT
) is then measured and defined as
∆V
DO
.
Since standby mode inhibits the output but keeps all biasing circuitry alive, the Standby Quiescent Current is similar to the
normal operating quiescent current.
Foldback Current Limit was characterized by pulse testing to remain below the maximum junction temperature (not
production tested).
The Reverse-Current Protection Threshold is the output/input differential voltage (V
OUT
- V
IN
) at which reverse-current
protection switchover occurs and the pass transistor is turned off. See the section
Reverse Current Protection
in the
Detailed Description.
Noise is tested using a bandpass amplifier with two poles at 10Hz and two poles at 10kHz.
