Overview
The NCP160AMX300TBG is a linear low-dropout (LDO) voltage regulator produced by onsemi. This device is designed to supply up to 250 mA of output current and is tailored to meet the stringent requirements of RF and analog circuits. It offers ultra-high power supply rejection ratio (PSRR), ultra-low output noise, and low quiescent current, making it ideal for applications requiring high stability and low noise.
The NCP160AMX300TBG operates within an input voltage range of 1.9 V to 5.5 V and is available in fixed voltage options ranging from 1.8 V to 5.14 V. It features a very low dropout voltage and excellent load and line transient response. The device is packaged in an ultra-small XDFN-4 package, measuring 1 mm x 1 mm, which is suitable for space-constrained designs.
