fs8853 pdf datasheet

The FS8853 is a low-dropout linear regulator that
operations in the input voltage range from +2.5V
to +9.0V and delivers 300mA output current.
The high-accuracy output voltage is preset at an
internally trimmed voltage 2.5V or 3.3V. Other
output voltages can be mask-optioned from 1.3V
to 4.5V with 100mV increment, except
FS8853-29Cx which has 2.85V output voltage.
The FS8853 consists of a 1.25V bandgap
reference, an error amplifier, and a P-channel
pass transistor. Other features include
short-circuit protection and thermal shutdown
protection. The FS8853 devices are available in
TO-92, SOT-89 and SOT-23 packages.
