MAX1963 Low-Input-Voltage / 300mA LDO Regulators with RESETin SOT and TDFN

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 (M.
