Low-Input-Voltage, 300mA LDO
Regulators with RESET in SOT and TDFN
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 i...
