3 Description
TL431LI-Q1/TL432LI-Q1 are pin-to-pin
Replacement for TL431-Q1/TL432-Q1. TL43xLI-Q1
Good stability and low temperature drift
(VI(dev)) and low reference current (Iref)
Improve system accuracy.
TL431-Q1 is a three-pin adjustable shunt
Regulators exceeding specified thermal stability
Suitable for automotive temperature range. of
The output voltage can be set to any value from VREF
(approx. 2.5 V) to 36 V with two external
resistor (see Figure 28). This device has a typical
Output impedance 0.2 Ω. Active output circuit
provides a sharp turn characteristic that makes this
device is an excellent replacement for Zener diodes
many applications, such as shipboard control,
Adjustable power supply, switching power supply
supply.
TL432-Q1 has the exact same function
such as the TL431-Q1 device, but
There are different pinouts for DBZ packages.
