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
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.
The demonstration board layout is available in Gerber file format. Please contact your Vishay Siliconix sales representative or
distributor for a copy.
