The AAT2605 is a member of Skyworks‘ Total Power Management IC （TPMIC?） product family. It contains five fully integrated 300mA low dropout （LDO） regulators in a small Pb-free 14-pin 3mm x 3mm TDFN package， making it ideal for space-constrained systems. The AAT2605 features low power consumption， low dropout， and high noise immunity from the input power supply. Each channel consumes a mere 30μA of current when enabled， features 250mV of dropout at 250mA and 68dB of power supply rejection at 10kHz. Each channel has its own enable pin and uses a small 1μF output capacitor. Output voltages are factory One Time Programmable （OTP） between 0.6V and 3.7V with 100mV increment and typical regulation accuracy is ±1%. LDO1 and LDO2 share the same input voltage， as do LDO3 and LDO4 while LDO5 has its own independent input. The AAT2605 is a safe solution that integrates an overcurrent limit for each channel and an over-thermal protection. The device is rated over a temperature range of -40°C to 85°C.
