The NCP562SQ15T1G is a kind of voltage regulator device manufactured by ON Semiconductor and comes in the form of a 6-pin SOT-23 package. Generally, it is meant to be encapsulated in a TSSOP with the possibility of a Mylar wrap.

Voltage regulators are used in a variety of applications, ranging from regulating the voltage of battery operated equipment, to providing clean and stable power for computer systems. The NCP562SQ15T1G linear voltage regulator is specifically designed for battery operated applications that require both low quiescent current and low dropout (LDO) performance.

The NCP562SQ15T1G is a low dropout (LDO) linear voltage regulator featuring low quiescent current, low dropout voltage, fast transient response, wide temperature range and logic control for output voltage selection. It has a single output of 5 V±1.5%, and a standard operating temperature range of -40°C to +85°C. A logic pin controls the output voltage enables/disable function with an integrated thermal shutdown feature.

The NCP562SQ15T1G operates within the input voltage range of 2.7 V to 15 V. It provides an output current of up to 150 mA with an adjustable output voltage range of 1.7V to 5.5V. The quiescent current is one of the primary benefits of the NCP562, offering a low quiescent current of only 65 μA, making it an ideal choice for battery operated applications.

The NCP562SQ15T1G is a popular choice for all sorts of battery powered applications, such as handheld communication devices, consumer entertainment products, automotive and industrial control systems, as well as battery operated equipment, because of its low quiescent current and wide range temperature support. It is capable of regulating the output voltage within a ±1% accuracy over temperature, providing excellent line and load regulation.

At the heart of the NCP562SQ15T1G is a voltage reference, a series pass transistor, an error amplifier and the necessary resistive and capacitor network components. The device has a dropout voltage of 210mV and a common mode rejection ratio of 40dB while operating in dropout conditions. The NCP562 runs with a efficiency of up to 95%.

The NCP562SQ15T1G also offers logic control with a logic enable/disable input. The NCP562 can be enabled with a logic signal, when logic is high, the regulator is in normal operation, when logic is low, the regulator is in the disable access. To protect the device from possible over-current or thermal damage, it has an integrated thermal protection circuit that halts the power dissipation when the temperature rises above a certain threshold.

To sum up, the NCP562SQ15T1G is a low dropout linear voltage regulator device offered by ON Semiconductor as an ideal choice for battery-operated applications requiring low dropout voltage, low quiescent current, and an adjustable output voltage range. It is capable of regulating the output voltage within a ±1% accuracy over temperature, providing excellent line and load regulation with a common mode rejection ratio of 40dB and an efficiency of up to 95%.
