AME4311
Low Voltage Shunt Regulator
n General Description
n Functional Block Diagram
The AME4311 is a low volatge version of the industry
standard 431 shunt regulator. The AME4311 reference is
set to 1.24 volts. The output voltage can be set to any
value between 1.24V and 8V with two external resistors.
(For factory set internal feedback resistors see the
AME4312.) When used with an optocoupler these de-
vices are ideal for isolated 3.3V switching supplies.
V+
Analog Microelectronics offers this part in a TO-92 pack-
age as well as the space saving SOT-23 and SOT-25
packages.
REF
For isolated switching power supplies requiring volt-
ages lower than 2.7V see the AME4315.
