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.

Absolute Maximum Ratings
Input voltage VIN to GND -------------------------------------------------------------------------------------------------- 10V
Output current limit, I(LIMIT) ----------------------------------------------------------------------------------------------- 0.5A
Continuous power dissipation, PD (T= TJ -TA = 100°C)
SOT-23-5 ------------------------------------------------------------------------------------------------------------------------------------------ 0.40W
SOT-89-5 ------------------------------------------------------------------------------------------------------------------------------------------ 0.55W
* The power dissipation values are based on the condition that junction temperature TJ and ambient
temperature TA difference is 100°C.
Junction Temperature, TJ ------------------------------------------------------------------------------------------------ +155°C
Storage temperature range, TSTG ----------------------------------------------------------------------- -55°C to +150°C
Operating junction temperature range ------------------------------------------------------------------ -40°C to +125°C
Lead temperature (soldering, 10sec) --------------------------------------------------------------------------------- 260°C
* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only, and function operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated
conditions for extended periods may affect device reliability.
