designed to provide 3.3V from a 5V supply. It is a
true low dropout regulator, it can hold its 3.3V
output in regulation with input voltages as low as
4.5V.
The regulator is available in a variety of
hermetically sealed packages and has the option
of being screened to both JAN and Space levels

1) Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating
the device outside of its rated operating conditions.
2) Dropout voltage is defined as the input-output differential voltage where the regulator output drops to a value that is 100 mV below
the value that is measured at VIN = 5V.
3) Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal
shutdown.
