FS8853A
300mA LDO Linear Regulator with ON/OFF Control
General Description
The FS8853A is a low-dropout linear regulator
with ON/OFF control. The device operates in the
input voltage range from +2.5V to +9.0V and
delivers 300mA output current.
The high-accuracy (±35mV) output voltage is
preset at an internally trimmed voltage 2.5V,
2.85V or 3.3V. Other output voltages can be
mask-optioned from 1.3V to 5.0V with 100mV
increment, except FS8853A-29Cx which has
2.85V output voltage.
The FS8853A consists of a 1.25V reference
compare amplifier, a P-channel pass transistor,
and an enable/disable logic circuit. Other
features include short-circuit protection and
thermal shutdown protection. The FS8853
devices are available in SOT-89-5 and
SOT-23-5 packages.
