DATA SHEET 300m A LDO Linear Regulator with µP Reset General Description The AAT3258 bines a high performance, low noise, 300m A low dropout (LDO) linear regulator with a microprocessor reset monitor. The 300m A output capability of the LDO regulator makes this device ideal for use with microprocessors and DSP cores in portable products. The microprocessor reset monitor section has very low quiescent current consumption and has an active low reset output. The AAT3258 has separate input pins for the reset monitor and LDO regulator so they may be operated from independent sources for increased design flexibility. This device Features very low quiescent current, typically less than 71µA. The LDO regulator has low dropout voltage, typically 400m V at the full output current level, making it ideal for portable applications where extended battery life is critical. The AAT3258 LDO regulator section has plete over-current/short-circuit and over-temperature protection circuits to...
