Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (TJ) within the

operating temperature range, unless otherwise noted. When operating C and E grade parts up to a TJ of +125°C, expect

performance similar to M grade specifications. For TJ between +125°C and +150°C, the output voltage may drift more.

(VIN - VOUT) is limited to keep the product (IOUT x (VIN - VOUT)) 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

TJ = +125°C is guaranteed by guard banding tests at TJ = +85°C and +70°C.

Dropout Voltage is (VIN - VOUT) when VOUT falls to 100mV below its nominal value at VIN = (VOUT + 2V). For example, the

MAX883 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.

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 (VOUT - VIN) 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.
