The MAX1793 low-dropout linear regulator (LDO) operates from +2.5V to +5.5V and delivers a guaranteed 1A load current with a low 210mV dropout. The high-accuracy (1%) output voltage is preset at an internally trimmed voltage (see Ordering Information) or can be adjusted from 1.25V to 5.0V with an external resistordivider. An internal PMOS pass transistor allows a low 125A supply current, making the MAX1793 ideal for batteryoperated portable equipment. Other features include a built-in reset output, low-power shutdown, and short-circuit 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.
