Overview
The NCP102SNT1G, produced by onsemi, is a low dropout linear regulator controller designed for applications requiring high-current and ultra-low dropout voltages. This device is packaged in a space-saving TSOP-6 package and is RoHS compliant. It features an extremely accurate 0.8 V (±2%) voltage reference, which is guaranteed over the complete supply and temperature ranges. The NCP102SNT1G allows for the implementation of sub 1 V voltage supplies and is highly versatile due to its ability to use an external N-Channel MOSFET, adapting to various system requirements for current and dropout voltage.
