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.
An internal PMOS pass transistor allows the low supply
current to remain independent of load and dropout volt-
age, making these devices ideal for portable battery-pow-
ered equipment such as personal digital assistants
(PDAs), cell phones, cordless phones, and notebook com-
puters. Other features include logic-controlled shutdown,
short-circuit protection, and thermal-overload protection.
