Note 1:

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.

Note 2:

(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.

Note 3:

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.

Note 4:

Since standby mode inhibits the output but keeps all biasing circuitry alive, the Standby Quiescent Current is similar to the

normal operating quiescent current.

Note 5:

Foldback Current Limit was characterized by pulse testing to remain below the maximum junction temperature (not

production tested).

Note 6:

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.

Note 7:

Noise is tested using a bandpass amplifier with two poles at 10Hz and two poles at 10kHz.

ELECTRICAL CHARACTERISTICS (continued)

(VIN = 6V (MAX883) or VIN = 4.3V (MAX882/MAX884), COUT = 2.2µF, STBY or OFF = VIN, SET = GND, LBI = VIN, TJ = TMIN to TMAX,

unless otherwise noted. Typical values are at TJ = +25°C.) (Note 1)
