Description

The Si9181DB/Si9182DB 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 Si9181DB/Si9182DB 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 switching load can be adjusted easily to simulate the actual load conditions. Provisions are made to measure the ground current and output noise accurately.The demonstration board uses surface mount and through-hole components and is fully assembled and tested for quick evaluation. The test points are provided for the closed-loop response measurement.Included in this document are the Bill-Of-Materials, Schematics, PCB Layout of the Demo Boards and actual waveforms/graphs.
