    SLVS555K – NOVEMBER 2004 – REVISED SEPTEMBER 2016 TLVH431, TLVH432 Low-Voltage Adjustable Precision Shunt Regulators
    1 Features 3 Description The TLVH431 and TLVH432 devices are low-voltage
    3-terminal adjustable voltage references, with
    specified thermal stability over applicable industrial
    and commercial temperature ranges. Output voltage
    can be set to any value between VREF (1.24 V) and
    18 V with two external resistors (see Figure 19).
    These devices operate from a lower voltage (1.24 V)
    than the widely used TL431 and TL1431 shuntregulator references. 1 Low-Voltage Operation: Down to 1.24 V
    Reference Voltage Tolerances at 25В°C
    – 0.5% for B Grade
    – 1% for A Grade
    – 1.5% for Standard Grade
    Adjustable Output Voltage, VO = VREF to 18 V
    Wide Operating Cathode Current Range:
    100 ОјA to 70 mA ...

    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
