LDL112D12R application field and working principle
LDL112D12R are part of a wide range of fixed voltage linear regulators (LVR) products offered by Linear Technology Corporation. LD series of LVRs feature low dropout voltage, low output current limit, high quiescent current and wide input voltage range. These devices are suitable for a variety of applications, including computer on-card regulation, telecom equipment regulation and battery voltage regulation.
The LD112D12R is a low dropout linear voltage regulator with internal current limit and thermal shutdown protection. It is used to regulate a voltage from a power supply to a lower voltage used in a system. The LD112D12R enables greater flexibility of adjustable output voltage, making it ideal for operation in lower voltage applications.
The working principle of the LD112D12R is based on the fact that a linear voltage regulator regulates the output voltage by monitoring the voltage drop across its current regulator. The internal transistor will self-adjust its base current to adjust the output voltage to maintain its output voltage across the load. It works by sinking current from its controlled output terminal (VOUT) and pulling current from the input power terminal (VIN) to maintain its reference voltage.
The LD series of LVRs have high power efficiency, low quiescent current, low dropout voltage and wide input voltage range. It is suitable for a wide variety of applications, including computer on-card regulation, communication equipment regulation and battery voltage regulation. The device also features low output current limit, adjustable output voltage and thermal shutdown protection.
The LD112D12R device is mainly used in computer on-card regulation applications due to its low dropout voltage, low quiescent current and wide input voltage range. The device is well suited for low voltage applications such as memory card applications. The device is also suitable for use in communications equipment such as VOIP systems, consumer electronics such as GPS units, and industrial equipment such as servo motors.
LDL112D12R are designed for use in battery applications as well. These devices feature low dropout voltage, low quiescent current and wide input voltage range. This makes them well suited for applications such as laptop computers and mobile phones where battery voltage regulation is crucial for a longer battery life.
In conclusion, LD112D12R linear voltage regulator are ideal for applications due their low dropout voltage, low quiescent current and wide input voltage range. These devices feature integrated thermal shutdown protection and low output current limit. These features make them ideal for a variety of applications, including computer on-card regulation, telecom equipment regulation and battery voltage regulation.
