MAX1589A
Low-Input-Voltage, 500mA LDO
Regulator with RESET in SOT and TDFN
General Description
The MAX1589A low-dropout linear
regulator operates from a +1.
62V to +3.
6V supply and delivers a guaranteed 500mA continuous load current with a low 175mV dropout.
The high-accuracy (±0.
5%) output voltage is preset to internally trimmed voltages from +0.
75V to +3.
0V.
An active-low, open-drain reset output remains asserted for at least 70ms after the output voltage reaches regulation.
This device is offered in 6-pin thin SOT23 and 6-pin, 3mm x 3mm thin DFN packages.
An internal pMOS pass
transistor maintains low supply current, independent of load and dropout voltage, making t...
