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 CBP 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.
