General Description
The MAX1963/MAX1976 low-dropout linear regulators operate from a +1.62V to +3.6V supply and deliver a guaranteed 300mA continuous load current with a low 100mV dropout. The high-accuracy (±0.5%) output voltage is preset to an internally trimmed voltage in the +0.75V to +3.0V range. An active-low, open-drain reset output remains asserted for at least 2.2ms (MAX1963) or 70ms (MAX1976) after the output voltage reaches regulation. These devices are offered in 6-pin thin SOT23 and 6-pin 3mm x 3mm thin DFN packages.
