AAT3258 300mA LDO Linear Regulator with μP Reset
The AAT3258 combines a high performance, low noise, 300mA low dropout (LDO) linear regulator with a microprocessor reset monitor. The 300mA 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 400mV at the full output current level, making it ideal for portable applications where extended battery life is critical. The AAT3258 LDO regulator section has complete over-current/short-circuit and over-temperature protection circuits to guard against extreme operating conditions. The device also has an active output pull-down function when disabled. The AAT3258 is available in a Pb-free, space-saving 8-pin TSOPJW package. This device is capable of operation over a -40°C to +85°C temperature range.
