The NCV33269DTRK-012 is a 5th generation voltage regulator from ON Semiconductor. It is a linear voltage regulator, which is a type of power management integrated circuit (PMIC). This voltage regulator is designed to provide a regulated and stable output voltage, given a range of input voltage, under varying load conditions. It features tight output voltage regulation and low ripple. It is widely used in automotive, industrial and consumer applications.

The NCV33269DTRK-012 operates by allowing a voltage to be regulated with minimal power loss and mean time before failure (MTBF). Its architecture allows it to remain active, while other components of the system are dormant. Its low operating current and high power output allow it to be an efficient, cost-effective way to control power.

The NCV33269DTRK-012 offers an adjustable output voltage range from 0.8V to 5V with maximum output current up to 800mA. Its extremely low dropout (LDO) voltage of 150mV and a quiescent current of only 27uA at 500mA make it suitable for battery-operated applications with extra-long battery life. With its wide-ranging input voltage options of 4.5V-28V, the device is well suited for both switch mode and linear regulators applications.

The device is designed with a 5.75” x 3.78” footprint, which makes it an attractive option for space-constrained designs. Its maximum power dissipation of 540mW also makes it suitable for a wide range of power applications. The NCV33269DTRK-012 also features thermal shutdown and output short-circuit protection.

The NCV33269DTRK-012 is a low-dropout (LDO) standard linear voltage regulator. Its working principle is relatively simple. It applies the same principle of regulating voltage used by the voltage regulator tubes in pre-electronic times. The principle involves a reference voltage source, a differential amplifier and an output transistor.

The reference voltage source is used to generate a reference voltage, or a set point, which is compared with the input voltage. If the input voltage is below the reference voltage, then the output transistor is turned off. The ratio of the voltage difference between the reference voltage and the output voltage is compared to decide how much current should be allowed to flow through the output transistor.

This type of linear voltage regulator offers precise output voltage regulation even under varying input and load conditions. Its output can be adjusted over a wide range by changing the reference voltage. This allows it to be used in a variety of applications.

Overall, the NCV33269DTRK-012 is an excellent choice for an alternatively sourced linear voltage regulator for automotive, industrial and consumer applications that require a precise and consistent output voltage. It is an ideal option for space-constrained designs, offering an adjustable output voltage range, a quiescent current of only 27uA, a maximum power dissipation of 540mW, along with its 5.75” x 3.78” size.
