NCP508SQ18T1G Description

Short technical summary and product information.

The NCP508SQ18T1G is a fixed-output, positive linear voltage regulator from onsemi designed to deliver a stable 1.8V output at up to 50mA. It operates with a maximum input voltage of 13.0V and features a typical dropout voltage of 140mV at 30mA load and 0.18V at 50mA load, making it suitable for low-dropout applications.

 

This regulator offers excellent ripple rejection of 70dB at 1kHz and very low output noise of 39µVrms without a bypass capacitor, making it ideal for noise-sensitive analog and RF circuits. It includes over-current and over-temperature protection, as well as an enable control feature for power management.

 

The device is available in a surface-mount SC-88A (SC-70-5/SOT-353) package and also supports a WDFN6 package option. It operates over a junction temperature range of -40°C to +125°C, with a maximum junction temperature of +125°C.
