NCV502SN33T1G is a linear voltage regulator PMIC (Power Management Integrated Circuit) which can provide up to 3.3A of output current. It is designed for use in single-cell Li Ion battery applications, where the regulator supplies a core powered logic circuit. The device operates in a wide input voltage range from 2.7V to 6.5V and provides fixed 3.3V adjustable output voltage.

NCV502SN33T1G is a low cost, small size, and high output current regulator suitable for space sensitive applications. It has a shutdown mode when the enable pin is left floating, and it has a current limit protection function in case of an overload condition. The device also has an internal thermal shutdown protection, as well as an output brownout protection.

The device has an adjustable reference voltage that is generated using an internal feedback network. The reference voltage can be set in two stages, by controlling an internal resistor divider, or by applying an external signal to the reference pin. This feature allows the device to control voltage in applications such as Power over Ethernet (PoE) systems, where the output voltage must be set accurately, and then maintained at that level.

The output voltage of NCV502SN33T1G is regulated by an external series P-type MOSFET transistor. The MOSFET is driven by an internal feedback loop which monitors the output voltage and turns on the output MOSFET transistor until the voltage reaches the programmed reference voltage. Additionally, the device has an internal voltage extend circuit to prevent overshoot of the output voltage.

The NCV502SN33T1G is designed to reduce system power dissipation and heat generation, and has an internal thermal protection circuit. It uses a low-noise linear regulator guarantee-to-deliver top-tier performance and performance stability. Its architecture also allows it to consume very low quiescent current while providing high current stability.

In summary, NCV502SN33T1G is a linear voltage regulator PMIC suitable for space sensitive applications. It is specifically designed for use in single-cell Li-Ion battery applications, where the regulator supplies a core powered logic circuit. With its adjustable reference voltage, it can be used in applications such as PoE systems. It has a shutdown mode when the enable pin is left floating, current limit protection, internal thermal shutdown and output brownout protection. The device also has a low-noise linear regulator that reduces system power dissipation, while consuming very low quiescent current and providing high current stability.
