NCP502SQ30T1G Description

The NCP502SQ30T1G is a linear regulator IC designed for power management applications, manufactured by onsemi. This device is part of the Power Management (PMIC) category and is known for its fixed output voltage configuration. It offers a maximum input voltage of 12V and a fixed output voltage of 3V, capable of delivering up to 80mA of output current. The regulator is designed with a single regulator output, ensuring a positive output configuration. It features a low quiescent current of 40 µA and a maximum supply current of 90 µA, making it highly efficient for low-power applications.

The NCP502SQ30T1G has a dropout voltage of 1.2V at 80mA, which is relatively low compared to similar devices, allowing it to maintain regulation even at low input-to-output voltage differentials. This feature is particularly beneficial in battery-powered applications where the input voltage may drop significantly over time. The regulator also boasts a high power supply rejection ratio (PSRR) of 55dB at 1kHz, ensuring minimal noise and ripple on the output voltage.

The device is housed in a surface-mount SC88A package, which is suitable for compact and space-constrained designs. It is available in a tape & reel (TR) packaging format, facilitating automated assembly processes. The NCP502SQ30T1G is rated for a moisture sensitivity level (MSL) of 1, indicating it is unaffected by moisture and suitable for unlimited storage periods.
