S7812BA is a low voltage, low drop-out voltage regulator. This versatile device is often used in battery-powered applications such as for digital audio, portable electronics, and embedded systems, and is particularly suitable for incorporating capacitors with bypass to achieve high-efficiency power conversion. Due to its low output voltage less than 1.2V, it is also suitable for applications requiring low power consumption, such as lithium-ion battery-powered portable applications.

The S7812BA is a CMOS integrated circuit (IC) which runs at 3.3 Volts and, depending on the version and the application, can support up to 19 Watts of power supply output. It integrates a low-drop Vin-V0 voltage regulator and a current-limit/low-battery protection circuit. The combination of its wide input voltage range, low quiescent current, high precision reference voltage, and fast transient response offers design flexibility and a wide range of features.

The S7812BA has four pins. VDD is its power supply line and GND is the ground. In is the input voltage line which must always be higher than VOUT (output voltage). The low-dropout voltage regulator will try to maintain the output voltage below VOUT until the voltage on VIN drops below it. The STAT pin serves as an output status indicator for both its current-limit and low-battery protection circuits.

The current-limit protection circuit is used to protect the load device from damage due to high current draw. The regulator will automatically reduce the output voltage to protect the load. It can also be used in conjunction with the low-battery protection circuit to decrease current draw when the input voltage drops below VOUT.

The low-battery protection circuit prevents the output voltage from exceeding VOUT because the regulator will shut down when VIN drops below VOUT. This is especially useful when the battery is depleted or when the input voltage is too low. When the input voltage rises again, it will automatically resume operation.

The S7812BA can provide output over a wide range of voltages, meaning it can be used as a multiple voltage rail regulator. This means it is suitable for applications that require multiple output voltages on separate lines.

The S7812BA is an efficient, reliable and versatile regulator which can offer good performance in applications which require low power consumption. Its multiple outputs make it suitable for a variety of applications and it is widely used in consumer, automotive and industrial electronics.
