POST OFFICE BOX 655303

description

The TL1431 is a precision programmable

reference with specified thermal stability over

automotive,

commercial,

and

military

temperature ranges. The output voltage can be

2.5 V) and 36 V with two external resistors (see

Figure 16). This device has a typical output

impedance of 0.2

Ω. Active output circuitry

provides a very sharp turnon characteristic,

making the device an excellent replacement for

zener diodes and other types of references in

applications

such

as

onboard

regulation,

adjustable power supplies, and switching power

supplies.

The TL1431C is characterized for operation over

the commercial temperature range of 0

°C to

70

°C. The TL1431Q is characterized for

operation over the full automotive temperature

range of –40

°C to 125°C. The TL1431M is

characterized for operation over the full military

temperature range of –55

°C to 125°C.
