Description
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, accu-
rate low voltage regulation is provided without the ineffi-
ciencies 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 space-
saving ceramic capacitors as small as 0402 case size.
The FAN2564 is available in 4-bump 0.5mm pitch wafer-
level chip-scale package (WLCSP) and a 6-lead 2 x
2mm ultra-thin molded leadless package (UMLP).
