General Description
The MAX1963A/MAX1976A low-dropout linear regula-
tors 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 (MAX1963A)
or 70ms (MAX1976A) after the output voltage reaches
regulation. These devices are offered in thin SOT23 and
thin DFN packages. An internal pMOS pass transistor
allows the low supply current to remain independent of
load and dropout voltage, making these devices ideal for
portable battery-powered equipment.
