MAX8869

19-1692; Rev 0; 8/00 1A, MicroCap, Low-Dropout, Linear Regulator General Description The MAX8869 low-dropout linear regulator operates from a +2.7V to +5.5V input and delivers a guaranteed 1A load current with a low 200mV dropout. The highaccuracy (±1%) output voltage is preset at +5V, +3.3V, +2.5V, +1.8V, or +1.0V or is adjustable from +0.8V to +5V with an external resistor-divider. The MAX8869 uses MicroCap™ technology and requires only a small 1µF output capacitor for guaranteed stability. An internal PMOS pass transistor allows low 500µA supply current, making this regulator useful for networking and telecom hardware as well as battery-operated equipment. Other features include softstart, low-power shutdown, short-circuit protection, and thermal shutdown protection. The MAX8869 is available in a 1.5W, 16-pin TSSOP package, which is 30% smaller than a SOT223 and only 1.1mm high. o Guaranteed 1A Output Current o Stable with COUT = 1µF o Low 200mV Dropout at 1A o ±1% Output Voltage Accuracy Preset at +5V, +3.3V, +2.5V, +1.8V, or +1.0V and Adjustable from +0.8V to +5.0V o 54dB PSRR at 100kHz o Adjustable Soft-Start o 3ms Reset Output o Foldback Output Current Limit o Thermal Overload Protection o High-Power 16-Pin TSSOP Package (1.5W) 30% Smaller than SOT223 (only 1.1mm high) Features MAX8869 ________________________Applications Telecom Hardware Network Equipment Mobile Phone Base Stations Personal Computers Notebook Computers PART MAX8869EUE50 MAX8869EUE33 MAX8869EUE25 M...
