The Si9181DQ/Si9182DH are the extremely low drop CMOS linear regulator ICs operating from 2-V to 6-V input. These devices offer ultra-low ground current and low dropout to extend the battery life in portable electronics. The demo boards are designed to verify different features easily and quickly. The input and output capacitors are selected to meet the specified noise and transient requirement. The device features the use of low ESR, low cost multi-layer ceramic capacitors. The Si9181DB/Si9182DB are provided with a MOSFET switch along with other components to measure the load transient response. The slew-rate of the
