SLVS543O – AUGUST 2004 – REVISED JANUARY 2015 TL43xx Precision Programmable Reference
1 Features 3 Description The TL431 and TL432 devices are three-terminal
adjustable shunt regulators, with specified thermal
stability over applicable automotive, commercial, and
military temperature ranges. The output voltage can
be set to any value between Vref (approximately
2.5 V) and 36 V, with two external resistors. These
devices have a typical output impedance of 0.2 О©.
Active output circuitry provides a very sharp turn-on
characteristic, making these devices excellent
replacements for Zener diodes in many applications,
such as onboard regulation, adjustable power
supplies, and switching power supplies. The TL432
device has exactly the same functionality and
electrical specifications as the TL431 device, but has
different pinouts for the DBV, DBZ, and PK packages. 1 Reference Voltage Tolerance at 25В°C ...

Designing Overcurrent protection for TPL7407L Peripheral Driver
Microcontroller units (MCUs) are generally limited with lower drive on the I/Os. Most of the applicationsrequiring MCU boards to drive high-current loads need discrete implementation and additional components, which use a lot of board space. This board space is called a peripheral driver section. The TPL7407L device is an integrated peripheral driver with seven channel drivers inside. The TPL740
