DESCRIPTION
The Si9183 is a high performance yet size saving 150-mA
CMOS LDO (low dropout) voltage regulator. Its ultra low
ground current and dropout voltage prolong battery life in
portable electronics. The device provides LINE/LOAD
transient response and ripple rejection superior to that of
Bipolar or BiCMOS LDO regulators. It is designed to maintain
regulation while delivering 300-mA peak current. The Si9183
drives lower cost ceramic, as well as tantalum, output
capacitors. Stability is guaranteed from maximum load current
down to 0-mA load. An external noise bypass capacitor
connected to the device’s C
BP
pin will reduce the LDO’s
self-noise for low noise applications. The Si9183 includes a
shutdown feature that allows users to completely disable the
device and save power when no output is required.
The Si9183, in Thin SOT23-5 packaging, is available in two
versions (Version A or B). Version A offers low noise
performance, while Version B features adjustable output
voltage.
The Si9183 is available in both standard and lead (Pb)-free
packages.
