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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Notes
a. Room = 25_C, Full = −40 to 85_C.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. Typical values for dropout voltage at V
OUT
w 2 V are measured at
V
OUT
= 2.5 V, while typical values for dropout voltage at V
OUT
< 2 V are measured at V
OUT
= 1.8 V.
d. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the output voltage measured with a 1-V
differential, provided that V
IN
does not not drop below 2.0 V.
e. The device’s shutdown pin includes a typical 6-MW internal pull-down resistor connected to ground.
f. V
OUT
is defined as the output voltage of the DUT at 1 mA.
