Features

* n Forced and Automatic Bypass modes n Miniature 10-pin lead free micro SMD package n Only three tiny surface-mount external components required n Uses small ceramic capacitors n Low output voltage ripple ( < 10 mV typ) n Internal soft start n Current overload protection n No external compensation A

Applications

* It steps down an input voltage from 2.7V to 5.5V to a variable output from 1.5V to 3.25V up to 300 mA. Output voltage is set using a www. DataSheet4U. com VCON analog input for controlling power levels and efficiency of the RF PA. An internal bypass switch allows direct connection to the battery for
