The ACT670_ LDOs have typical current limit of 450mA and are available in high accuracy (1.5%) output voltages from 1.5V to 5V in 50mV increments. These products feature thermal shutdown protection and current limit with fold-back in short circuit. The ACT6700 is available in the SOT23-3 and SOT89-3 packages. The ACT6701 is available in the SOT23-5 package and includes a power-good indicator output. The ACT6702 is available in the SOT23-5 package and includes a low noise bypass pin for low noise applications. These products are ideal for portable information devices, cellular phones, and other batter...
