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 (V_CON) 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.
