The LDL112DR voltage regulator is a unique product that provides a linear regulated output voltage from an input voltage in its own particular range. It is a part of the PMIC - voltage regulators - linear category, and is commonly employed in applications requiring reliable power supply. This article will explore the LDL112DR′s application field and working principle.

Applications

The LDL112DR is typically employed in applications such as low voltage DC-DC converters, portable devices, automotive electronics, etc. It features a wide range of application possibilities due to its high current and power output capabilities and its exceptionally low quiescent current. This makes the LDL112DR well suited for battery powered and low power applications, such as portable music devices.

Furthermore, the LDL112DR is equipped with an advanced process of start-up characteristics, which makes the device suitable for any application requiring reliable power supply. It is important to point out that the LDL112DR can provide an output current that is up to 4 times higher than the traditional linear regulators.

Working Principle

The LDL112DR includes an LDO (low drop-out) circuit, which is used to regulate the output voltage of the device. This LDO circuit consists of a P-channel MOSFET and other components that act as a virtual ground. In normal operation, a voltage divider is formed between the input voltage, ground and a reference voltage. This reference voltage is then amplified to adjust the gate voltage of the MOSFET, effectively regulating the output voltage.

In order to ensure optimal operation, the LDL112DR is fitted with a built-in pre-bias voltage limiting circuit which is designed to protect the device from excessive voltage levels on the input side. The pre-bias voltage limiting circuit also enables smooth and noise-free start-up. The device is regulated by an external voltage divider circuit, which acts as a feedback loop to ensure the output remains constant.

In addition, the LDL112DR can be equipped with an enable pin for switching between different output voltage settings. This allows for a voltage optimization depending on the needs of the particular application. The device is incredibly efficient, reaching up to 96% power efficiency which further improves battery life and reduces heat dissipation.

Conclusion

In conclusion, the LDL112DR voltage regulator is a unique product that can be employed in a wide range of applications, due to its exceptional current, power, and efficiency capabilities. Its application field is wide, ranging from portable devices and automotive electronics, to low voltage DC-DC converters. It utilizes an LDO circuit with pre-bias voltage limiting, which enables reliable operation and enables the user to easily switch between different output voltage settings. Overall, the LDL112DR is a great solution for applications requiring reliable power.
