The LM3280 is a multi-functional Power Management Unit, optimized for low-power handheld applications such as Cellular Phones.

The LM3280 incorporates three low-dropout LDO voltage regulators and one step down PWM DC-DC converter with an internal Bypass FET. The step down converter's output voltage can be set using an analog input (VCON) for optimizing efficiency of the RF PA at various power levels. The LDO operates a nominal output voltage of 2.85V and maximum load current capability of 20mA for a reference voltage required by linear RF power amplifiers. The LM3280 additionally features a separate enable pin for each output.

The LM3280 is available in a 16-pin lead free DSBGA package.
