The AAT2783 provides three independently regulated DC outputs: two step-down (Buck) regulators and a single low input voltage, low drop-out (LDO) regulator. The input voltage range for the step-down regulators is 2.7V to 5.5V, while the LDO regulator allows inputs from 1.5V to 5.5V. The low input voltage LDO regulator allows high efficiency, step-down, low noise outputs. In addition, the LDO input may be connected to step-down outputs 1 or 2.
The Channel 1 and 2 step-down regulators AAT2783 can deliver up to 1000mA and 400mA output current, respectively. Step-down output voltages are set with external resistors. Switching frequency is set at 1.3MHz to ensure small external filtering components. Current mode control assures fast transient response and stable operation across the operating range. The Channel 3 LDO regulator can deliver up to 400mA with -80dB power supply rejection ratio (PSRR) and 65VRMS output noise with an optional bypass capacitor. The LDO output voltage is factory set with a default voltage of 1.20V. Independent enable and input pins are provided. The device consumes low quiescent current and provides high efficiency across the load range for maximum life in battery systems.
The AAT2783 is available in the Pb-free, 16-pin TDFN34 package and is rated over the -40C to 85C operating temperature range.
