  Linear Voltage Regulator  LM29408
 
Positive Fixed 8V Voltage Regulator in bare die form
Rev 1.1
3/11/17
Descrip  tion
Features:
The LM294 0-8 positive voltage regulator features
the ability to source 1A of output current with a dropout
veonlttiaregeteomf pt yepraictaulrley
0.5V &
range.
a
A
maximum
quiescent
of 1V over
current
the
reduction c ircuit has been included which reduces the
ground current when the differential between the input
voltage & th  e output voltage exceeds approximately
3V. The quiescent current with 1A of output current &
an input-ou tput differential of 5V is therefore only 30
mA. Higher quiescent currents only exist when the
regulator is  in the dropout mode (VIN - VOUT ≤ 3V).
ƒ Dropout voltage typically 0.5V @ IO = 1A
ƒ Output current in excess of 1A
ƒ Reverse battery protection
ƒ Internal short circuit current limit
ƒ Full Military Temperature Range.
