NCP694D12HT1G is a low dropout (LDO) regulator integrated circuit (IC) produced by ON Semiconductor. It is a three-terminal device. These devices are designed to provide a low voltage output with excellent load and line regulation over a wide range of ambient temperatures. The NCP694D12HT1G is suitable for use in a broad range of applications, including high-efficiency power supplies, uninterruptible power supplies (UPS) systems, automotive auxiliary power, telecom equipment, and high-precision medical electronics.

The NCP694D12HT1G is a low noise, low quiescent current, low power linear regulator. It is designed to be used with low voltage DC sources to provide a regulated output voltage. It offers a dropout voltage of 0.5V, a maximum peak-to-peak output noise of 5 mV, and a maximum line of 10 mV. It features short circuit protection and over temperature protection. The NCP694D12HT1G is designed to be used with a range of input voltages and can operate over a temperature range of -40°C to +125°C. The NCP694D12HT1G is available in a wide variety of configurations and packages.

The NCP694D12HT1G is a three-terminal device, with an input, output, and ground pin. The input pin is used to supply the voltage to be regulated. The output pin provides the regulated voltage and can be used for a variety of different applications. The ground pin is used for the return path of the electrical current. The input and output pins are relatively lightly loaded, which allows the regulator to provide a low output noise and excellent power supply rejection ratio (PSRR). The NCP694D12HT1G also features extremely low quiescent current, making it ideal for energy-sensitive applications.

The NCP694D12HT1G works by automatically sensing the input voltage, and adjusting its output as necessary to maintain a steady output voltage. This is achieved through a series of operating principles, including an error amplifier, voltage reference and a pass element, typically a field-effect transistor (FET). The error amplifier constantly monitors the output voltage and compares it with a reference voltage and adjusts the output voltage accordingly. The voltage reference pin is used to set the output voltage, and the pass element is used to regulate the output current. The NCP694D12HT1G includes a variety of protection features, such as over-current protection and over-temperature shutdown.

The NCP694D12HT1G is a versatile regulator IC and can be used in many applications. It is suitable for use in mobile phones, portable audio players and other portable devices, automotive auxiliary power supplies, uninterruptible power supplies (UPS), and small-signal control and sensing applications. NCP694D12HT1G can be used as a linear regulator in high-efficiency power supply designs, or as a low dropout regulator in low-noise power supplies. It is also suitable for use in systems requiring high-precision regulation, such as medical electronics, where the NCP694D12HT1G’s low power consumption and high PSRR makes it a good choice.
