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.
