MAX1793 - Low-Dropout / Low IQ / 1A Linear Regulator

General Description

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.

Key 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. 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.

19-1654; Rev 1; 11/00 Low-Dropout, Low IQ, 1A Linear Regulator MAX1793 General Description 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 125µA 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.
