The FS8856 is a low-dropout linear regulator
that operations in the input voltage range from
+2.5V to +6.5V and delivers 550mA 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 5.0V with 100mV increment, except
FS8856-29Cx which has 2.85V output voltage.
The FS8856 consist of a 1.25V reference
compare amplifier, and a P-channel pass
transistor. Other features include short-circuit
protection and thermal shutdown protection.
The FS8856 devices are available in TO-92,
SOT-89 and SOT-223 packages.
