NCP508SQ18T1G

NCP508SQ18T1G Description

The NCP508SQ18T1G from onsemi is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. This fixed-output regulator delivers a stable 1.8V with a maximum output current of 50mA, making it ideal for low-power devices. With an ultra-low quiescent current of 1 µA and a dropout voltage as low as 0.18V @ 50mA, it ensures efficient operation even in battery-powered systems. The device operates over an input voltage range of up to 7V and features 70dB PSRR (1kHz), minimizing noise for sensitive analog or digital loads. Packaged in a compact SC88A (SOT-353) footprint, it is optimized for surface-mount applications.
