General Description
The AAT2606 is a member of AnalogicTech’s Total Power
Management IC™ (TPMIC™) product family. It contains
six fully integrated 300mA low dropout (LDO) regulators
in a small, Pb-free 14-pin 3mmx3mm TDFN package,
making it ideal for space-constraint systems.
The AAT2606 features low power consumption, low drop-
out, and high noise immunity from the input power sup-
ply. Each channel consumes a mere 30μA of current
when enabled and features 250mV of dropout at 250mA
and 68dB of power supply rejection at 10kHz. Each chan-
nel 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%.
The AAT2606 is a safe solution that integrates an over-
current limit for each channel and over-thermal protec-
tion. The device is rated over a temperature range of
-40°C to 85°C.
