19-3684; Rev 1; 5/12 MAX1963A/MAX1976A Low-Input-Voltage, 300m A LDO Regulators with RESET in SOT and TDFN General Description The MAX1963A/MAX1976A low-dropout linear regulators operate from a +1.62V to +3.6V supply and deliver a guaranteed 300m A continuous load current with a low 100m V 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 (MAX1963A) or 70ms (MAX1976A) after the output voltage reaches regulation. These devices are offered in thin SOT23 and thin DFN packages. An internal p MOS pass transistor allows the low supply current to remain independent of load and dropout voltage, making these devices ideal for portable battery-powered equipment.
