Introduction of S-812C43AMC-C2XT2G

S-812C43AMC-C2XT2G is a type of PMIC (power management integrated circuit) designed for low-voltage applications. It is a low dropout linear regulator that offers an output voltage range of 0.6 to 1.6 V with a 3-pin SOT-23 package. This device is suitable for battery-powered systems and embedded applications such as cell phones and portable electronics.

Application Field of S-812C43AMC-C2XT2G

S-812C43AMC-C2XT2Gs are usually applied in battery-powered systems and embedded applications such as cell phones and portable electronics. Batteies are usually low voltage supply, which means linear regulators are preferred since a low dropout linear regulator like S-812C43AMC-C2XT2G can maintain a steady voltage and current output without having to drop the input voltage much. With that, the efficiency and power loss of the entire system can be kept lower, while providing a steady output even during low input voltage conditions.

In addition to that, the S-812C43AMC-C2XT2G is highly compatible with popular LDOs currently available in the market. It can replace the usual LDOs with better performance, increased efficiency and lower power loss. It is also ideal for space-restricted applications due to its ultra-small size – all in a 3-pin SOT-23 package.

Working Principle Of S-812C43AMC-C2XT2G

The S-812C43AMC-C2XT2G is a linear voltage regulator with a low dropout voltage of typically 150 mV at 90 mA load current. The device draws a quiescent current of only 0.45 μA when enabled, which can reduce the power loss in many battery-powered systems. The regulator employs a voltage feedback loop, where the error amplifier compares the output voltage to an internal reference voltage. When an output voltage droop occurs, the error amplifier increases the voltage level of the output signal until it reaches the original output voltage level.

For applications when a longer hold up time is needed, an additional PMOS pass transistor between the supply voltage and the output can be used. The PMOS transistor can be turned off before the output voltage drops, thus providing a much longer hold-up time compared to a simple series pass regulator.

The S-812C43AMC-C2XT2G also features current and thermal limit protections to protect the device from shock and over-current conditions. The device is also able to monitor the input voltage to provide an early warning for low supply conditions. This can be useful for battery-powered systems since it can help to provide a safeguard for the battery depletion.

Conclusion

The S-812C43AMC-C2XT2G is suitable for any battery-powered system or embedded application in need of a low dropout linear voltage regulator. It provides excellent line and load transient characteristics, as well as high efficiency with a low quiescent current while being capable of providing current or thermal protection to the system. The device also monitor the input voltage to provide an early warning for low supply conditions and can provide longer hold-up time.
