The output is over-current, overtemperature and short-circuit protected, with a current limiting approximately 275mA. It incorporates an error amplifier and temperature stabilized output voltage, as well as an optional built-in inhibit function, which can be enabled/ disabled by external control. Furthermore, it offers a ripple rejection of 72dB at 100Hz, low supply current into the Regulation Control terminal, current foldback protection, low shutdown current and output current limit.

The device is ideally suited for supplying analog circuits in portable application fields. The S-L2980A39MC-TF-G voltage regulator is implemented in a variety of applications, such as clock oscillators, continuous current limits, low dropout regulators, low noise linear regulators, power converters, pre-charged batteries and power management.

The S-L2980A39MC-TF-G regulator implies a basic working principle. The input voltage is compared to the internal reference voltage, by means of an error amplifier. Functionally, the output voltage remains constant while this control voltage is kept constant. Thus, the device can be used to create a very stable output voltage from an input voltage that varies over load (Vin). On the other hand, the output voltage is adjustable over the external resistors. The voltage output is stabilized by the temperature stabilization circuit on board.

The S-L2980A39MC-TF-G is designed for use in high-demand, high-power applications, including portable medical and industrial equipment, automotive systems, and consumer electronics. Its integrated low-power consumption, low dropout, high ripple rejection and high performance makes this device an ideal choice for a variety of power conditioning applications. Additionally, its integrated thermal regulation and overload protection further enhance its versatility in areas where low quiescent current and extended temperature range operation are required.

In summary, the S-L2980A39MC-TF-G voltage regulator is specifically designed for portable electronic equipment, making it an ideal choice for applications such as clock oscillators, continuous current limits, low noise linear regulators, power converters, pre-charged batteries, and power management. It offers the precision output of ±2% initially adjustable up to ±4% by external resistors at typical currents up to 300mA, combined with low quiescent current and extended temperature range operation. Moreover, it includes features such as error amplifier, temperature stabilized output voltage, optional built-in inhibit function, ripple rejection of 72dB at 100Hz, low supply current into the Regulation Control terminal, current foldback protection, low shutdown current and output current limit.
