Tl431 Application Note. Which can equate to much iq savings on the systems level. Tl431 d tl431a b series ncv431a b series scv431a programmable precision references the tl431a b integrated circuits are three terminal programmable shunt regulator diodes.
The tl431 and tl432 devices are three terminal adjustable shunt regulators with specified thermal stability over applicable automotive commercial and military temperature ranges. These monolithic ic voltage references operate as a low temperature coefficient zener which is programmable from v ref to 36 v with two external resistors. Atl431 offers the lowest minimum cathode current for regulation ika min and reference current iref of the 431 family of shunt references.
Abstract tl431 is a shunt voltage reference that is versatile in its form and function.
Abstract this application note will discuss ti s latest addition to its adjustable shunt regulator family atl431. Output voltage settable or programmable from 2 5v minimum reference up to 36 volts. Let s learn more about its specifications and application notes. These monolithic ic voltage references operate as a low temperature coefficient zener which is.
