1 / 11 page General Description The MAX1793 low-dropout linear regulator (LDO) oper- ates from +2.5V to +5.5V and delivers a guaranteed 1A load current with a low 210mV dropout. The high-accu- racy (±1%) output voltage is preset at an internally trimmed voltage (see the Ordering Information) or can be adjusted from 1.25V to 5.0V with an external resis- tor-divider. An internal pMOS pass transistor allows a low 125µA supply current, making the MAX1793 ideal for battery- operated portable equipment. Other features include a built-in reset output, low-power shutdown, and short-cir- cuit and thermal-overload protection. The MAX1793 is available in a 1.5W, 16-pin power TSSOP package, which is 30% smaller than a SOT223 package and only 1.1mm high. ________________________Applications Notebook Computers Cordless Telephones Cellular Phones Modems Handheld Instruments PDAs and Palmtop Computers Features o Guaranteed 1A Output Current o Low 210mV Dropout at 1A o Up to ±1% Output Voltage Accuracy Preset at 1.5V, 1.8V, 2.0V, 2.5V, 3.3V or 5.0V Adjustable from 1.25V to 5.0V o Reset Output (4ms Delay) o Low 125µA Ground Current o 0.1µA Shutdown o Low 115µVRMS Output Noise o Thermal-Overload Protection o Output Current Limit o Tiny TSSOP Power Package (1.5W) 30% Smaller than SOT223 (only 1.1mm high) Low-Dropout, Low IQ, 1A Linear Regulator ________________________________________________________________ Maxim Integrated Products 1 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 N.C.
