Note 1: Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (TJ) equal to the
operating temperature range. C and E grade parts may be operated up to a TJ of +125°. Expect performance similar to
M grade specifications. For TJ between +125°C and +150°C, the output voltage may drift more.
Note 2: (VIN - VOUT) is limited to keep the product (IOUT x (VIN - VOUT)) from exceeding the package power dissipation limits.
Note 3: Dropout Voltage is (VIN - VOUT) when VOUT falls to 100mV below its nominal value at VIN = VOUT + 2V. For example, the
MAX603 is tested by measuring the VOUT at VIN = 7V, then VIN is lowered until VOUT falls 100mV below the measured value.
The difference (VIN - VOUT) is then measured and defined as ∆VDO.
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 (VOUT - VIN) 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.
