... The MAX882/MAX883/MAX884 feature Dual Mode operation. In preset voltage mode, the MAX883’s out- put is set to 5V and the MAX882/MAX884’s output is set to 3.3V, using internal trimmed feedback resistors. Select this mode by connecting SET to ground. In preset voltage mode, impedances between SET and ground should be less than 100kΩ ...

... A low-logic input on the OFF pin shuts down the MAX883/MAX884. In this mode, the pass transistor, control circuit, reference, and all biases are turned off, and the supply current is reduced to less than 1µA. toler- SET LBO is undefined in OFF mode. Connect OFF to IN for normal operation ...

... STBY Power Dissipation and Operating Region Maximum power dissipation of the MAX882/MAX883/ MAX884 depends on the thermal resistance of the case and PC board, the temperature difference between the die junction and ambient air, and the rate of air flow. The power dissipation across the device is ...

... COPPER GROUND PAD AREA Figure 4. Typical Maximum Power Dissipation vs. Ground Pad Area The GND pins of the MAX882/MAX883/MAX884 SOIC package perform the dual function of providing an elect- rical connection to ground and channeling heat away. Con- nect all GND pins to ground using a large pad or ground plane ...

... LBO remains functional in stand- by mode for the MAX882, but is undefined in OFF mode for the MAX883 and MAX884. Tie LBI to IN when not used. Use a resistor-divider network as shown in Figure 6 to set the low-battery trip voltage. Current into the LBI input is ± ...

... Input Bypass Capacitor Normally, use 0.1µF to 10µF capacitors on the MAX882/ MAX883/MAX884 input. The best value depends pri- marily on the power-up slew rate of V and line transients. Larger input capacitor values pro- vide better supply-noise rejection and line-transient response, as well as improved performance, when the supply has a high AC impedance ...

... The current drawn by the MAX882’s OUT pin at 3.3V during reverse-current protection is typically 8µA. It should not be used with the MAX883 and MAX884, since the OFF pin is a logic input, and indeterminate inputs can cause the regulator to turn on intermittently, draining the battery. ...
