DATA SHEET AAT2605 Five-Channel 300mA LDO Regulator General Description Features The AAT2605 is a member of Skyworks Total Power 2.7V to 5.5V Operating Input Voltage Range Management IC (TPMIC) product family. It contains five 5 Outputs with Factory Programmable Voltages from fully integrated 300mA low dropout (LDO) regulators in a 0.6V to 3.7V small Pb-free 14-pin 3mm x 3mm TDFN package, making 300mA Output Current Per Channel it ideal for space-constrained systems. 3mmx3mm, 14-Pin TDFN Package 1% Typical Accuracy The AAT2605 features low power consumption, low drop- Low 30A Quiescent Current out, and high noise immunity from the input power sup- High PSRR (68dB 10KHZ) ply. Each channel consumes a mere 30A of current when 250mV Dropout Voltage at 250mA enabled, features 250mV of dropout at 250mA and 68dB Independent Enable of power supply rejection at 10kHz. Each channel has its Over-Current Protection own enable pin and uses a small 1F output capacitor. Over-Thermal Protection Output voltages are factory One Time Programmable (OTP) between 0.6V and 3.7V with 100mV increment and Applications typical regulation accuracy is 1%. LDO1 and LDO2 share the same input voltage, as do LDO3 and LDO4 while LDO5 Cellular Applications has its own independent input. Handheld Products Media Players (MP4 Players) The AAT2605 is a safe solution that integrates an over- Portable Navigation Devices (PND) current limit for each channel and an over-thermal pro- tection. The device is rated over a temperature range of -40C to 85C.
