UA78L12ACDG4

PMIC - Voltage Regulators - Linear

The UA78L12ACDG4 is a linear voltage regulator for high current applications. It is a three-terminal device with an adjustable output voltage from 3 V to 30 V. It provides up to 1.5 A of output current and features a low quiescent current. It has a low dropout voltage, so it only requires a small voltage differential between its input and output pins. This makes the device ideal for low voltage applications.

The UA78L12ACDG4 operates on an unregulated input supply voltage. It takes the unregulated input and converts it to a regulated output voltage. The voltage regulator maintains a constant output voltage through a feedback loop that continuously monitors the output voltage. The internal control circuit uses a comparison between the regulated output voltage and a reference voltage to adjust the current flow through the pass transistor.

The UA78L12ACDG4 is designed to provide protection against over-current and reverse polarity protection. It is designed to provide over-current protection by shutting down the device when the output current exceeds an over-current threshold. It also provides reverse polarity protection by shutting down the device when the output current is reversed.

The UA78L12ACDG4 features low noise performance. It features low power dissipation and high efficiency. It is stable with small output capacitors and low external parts count. It is also capable of withstanding large transient loads.

The UA78L12ACDG4 is suitable for applications such as battery powered equipment, telecommunication systems,and consumer electronics. It is also suitable for low voltage applications such as 3V to 5V power supplies, and outdoor systems with batteries.

Conclusion

The UA78L12ACDG4 is a linear voltage regulator suitable for high current applications. It provides adjustable voltage output from 3 to 30 volts. It provides over current and reverse polarity protection, and is capable of withstanding large transient loads. The UA78L12ACDG4 is suitable for a variety of applications such as battery powered equipment, telecommunications systems, and consumer electronics.
