The FAN2564 operates from a minimum input of 1.65V and provides outputs as low as 1.2V. Output current is guaranteed to 300mA, making this regulator ideal for digital loads.

The unique low input voltage capability and very low dropout make this device an ideal post regulator to a synchronous buck regulator. In this configuration, accurate low voltage regulation is provided without the inefficiencies typically related to linear regulators.

The enable pin can be used to initiate shutdown mode, where the operating current falls to an extremely low 10nA, typically.

The FAN2564 is designed to be stable with spacesaving ceramic capacitors as small as 0402 case size.

The FAN2564 is available in 4-bump 0.5mm pitch waferlevel chip-scale package WLCSP and a 6-lead 2 x 2mm ultra-thin molded leadless package UMLP .
