TL1431
Programmable Voltage Reference
■ Adjustable output voltage: V_REF to 36V
■ Sink current capability: 1 to 100mA
■ Typical output impedance: 0.22Ω
■ 0.4% and 0.25% voltage precision
Description
The TL1431 is a programmable shunt voltage
reference with guaranteed temperature stability
over the entire temperature range of operation.
The output voltage may be set to any value
between 2.5V and 36V with two external resistors.
The TL1431 operates with a wide current range
from 1 to 100mA with a typical dynamic
impedance of 0.2Ω.
