4 / 17 page 5V/3.3V or Adjustable, Low-Dropout, Low IQ, 200mA Linear Regulators 4 _______________________________________________________________________________________ Note 1: Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature (TJ) within the operat- ing temperature range, unless otherwise noted. Specifications to -40°C are guaranteed by design and not production tested. 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. 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 = -40°C to +85°C, unless otherwise noted. Typical values are at TJ = +25°C.)
