MAX1589A - 500mA LDO Regulator

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.

Features

  • include logic-controlled shutdown, short-circuit protection, and thermal-overload protection.

19-3664; Rev 0; 4/05 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.
