    SLVS139W – JULY 1996 – REVISED MARCH 2018 TLV431x Low-Voltage Adjustable Precision Shunt Regulator
    1 Features 3 Description The TLV431 device is a low-voltage 3-terminal
    adjustable voltage reference 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 6 V with two
    external resistors (see the Parameter Measurement
    Information section). These devices operate from a
    lower voltage (1.24 V) than the widely used TL431
    and TL1431 shunt-regulator references. 1 Low-Voltage Operation, VREF = 1.24 V
    Adjustable Output Voltage, VO = VREF to 6 V
    Reference Voltage Tolerances at 25В°C
    – 0.5% for TLV431B
    – 1% for TLV431A
    – 1.5% for TLV431
    Typical Temperature Drift
    – 4 mV (0°C to 70°C) ...

    Implementing a Buck Converter With the TPS23753A
    The TPS23753A is intended for isolated applications and does not incorporate an internal voltage-regulation error amplifier. Due to its integration and features it may be advantageous to use the TPS23753A in non-isolated applications. This application report shows additional circuits necessary to implement a low-side switch buck converter using the TPS23753A.

    Supplying TPS61200 With a Single Solar Cell (Rev. B)
    This application report explains how to use the TPS61200 in combination with a single solar cell to charge a battery or storage device. A characteristic of solar cells is the internal resistance that can vary from less than 10 Ω up to more than 100 Ω. Therefore it is important to control the load placed on the solar cell to ensure a reliable start-up of the application. This report describes an a

    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
