S-812C46AUA-C3AT2G is a low dropout (LDO) linear voltage regulator primarily designed for applications requiring rather high accuracy, low power consumption and low noise. The S-812C46AUA-C3AT2G is an advanced version of S-812 family regulators which feature low power consumption, and high reliability, long line and load transient response, adjustable output voltage, and excellent performance in high current applications.The S-812C46AUA-C3AT2G is based on the three terminal regulator topology known as a Low Dropout (LDO) regulator. The S-812C46AUA-C3AT2G series is designed to provide a regulated output voltage over a full range of input voltages. It takes an input voltage (Vin) usually between 3.8 V to 22 V and then outputs a regulated output voltage (Vout) typically between 1.2 V to 5.0 V depending on the particular model. The S-812C46AUA-C3AT2G is protected against a reverse input voltage applied. The S-812C46AUA-C3AT2G also incorporates over temperature, reversed polarity protection, over-current protection as well as protection from output open circuit.The S-812C46AUA-C3AT2G series is suitable for use in cellular phones, battery-powered systems, notebook computers, set-top boxes, portable instrumentation and other system requiring low voltage, high current and low cost. The S-812C46AUA-C3AT2G has a maximum quiescent current of 200uA with an input voltage range of 4.5V to 18V and can supply up to 2A of current with a dropout voltage of 140mV at a 2A load. The S-812C46AUA-C3AT2G also offers line and load transient response typically better than 20mV in 10ms and ripple rejection of 70dB. The S-812C46AUA-C3AT2G includes an enable pin, which may be used to enable or disable the regulator for power savings.The S-812C46AUA-C3AT2G offers many features that are beneficial in many applications. Its low quiescent current and low dropout voltage allow for power savings in battery powered applications. Its fast transient response with very low output voltage overshoot makes the S-812C46AUA-C3AT2G suitable for high current applications. Its Thermal protection circuit monitors die temperature and shuts down the output before the junction temperature exceeds +125 degree Celsius. The S-812C46AUA-C3AT2G is a linear regulator, meaning that it operates based on the principle of controlling the output voltage by controlling the input-to-output differential voltage. The S-812C46AUA-C3AT2G uses a voltage reference to compare the output voltage to its reference creating an error signal, which is then used to adjust the control element, usually a MOSFET, to keep the output voltage constant. The regulation error is small, usually only a few millivolts. In summary, the S-812C46AUA-C3AT2G is a low dropout, linear voltage regulator designed for applications requiring high accuracy, low power, and low noise. With its low quiescent current, low dropout voltage, fast transient response and thermal protection, the S-812C46AUA-C3AT2G is suitable for use in cellular phones, battery-powered systems, notebook computers, set-top boxes, and other systems requiring low voltage, high current and low cost. Additionally, the S-812C46AUA-C3AT2G’s enable pin can be used to enable or disable the regulator for power savings and ease of use in applications.
