Note 1:
Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (T
J
) equal to the
operating temperature range. C and E grade parts may be operated up to a T
J
of +125°. Expect performance similar to
M grade specifications. For T
J
between +125°C and +150°C, the output voltage may drift more.
Note 2:
(V
IN
- V
OUT
) is limited to keep the product (I
OUT
x (V
IN
- V
OUT
)) from exceeding the package power dissipation limits.
Note 3:
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
MAX603 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
.
Note 4:
Foldback Current Limit was characterized by pulse testing to remain below the maximum junction temperature.
Note 5:
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.
Note 6:
Noise is tested using a bandpass amplifier with two poles at 10Hz and two poles at 10kHz.
