TL432-Q1
- Qualified for automotive applications
- AEC-Q100 test guidance with the following:
- Device temperature grade 1: –40°C to 125°C ambient operating temperature range
- Reference voltage tolerance at 25°C:
- 1% (A Grade)
- 0.5% (B Grade)
- Typical temperature drift:
- 14 mV (Q Temp)
- Low output noise
- 0.2-Ω Typical output impedance
- Sink-current capability: 1 mA to 100 mA
- Adjustable output voltage: VREF to 36 V
The TL431LI-Q1 / TL432LI-Q1 are pin-to-pin alternatives to TL431-Q1 / TL432-Q1. TL43xLI-Q1 offers better stability, lower temperature drift (VI(dev)), and lower reference current (Iref) for improved system accuracy.
The TL431-Q1 is a three-pin adjustable shunt regulator with specified thermal stability over applicable automotive temperature ranges. The output voltage can be set to any value from VREF (approximately 2.5 V) to 36 V, with two external resistors (see Figure 28). This device has a typical output impedance of 0.2 Ω. Active output circuitry provides a sharp turnon characteristic, making this device an excellent replacement for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.
The TL432-Q1 has exactly the same functionality and electrical specifications as the TL431-Q1 device, but has a different pinout for the DBZ package.
