ADI's ADP7183 is a complementary metal oxide semiconductor (CMOS), low dropout (LDO) linear regulator that operates from -2.0 V to -5.5 V and provides up to -300 mA of output current. This LDO regulator is ideal for regulation of high performance analog and mixed-signal circuits operating from -0.5 V down to -4.5 V. Using an advanced proprietary architecture, the ADP7183 provides high PSRR and low noise, and achieves excellent line and load transient response with a small 4.7 μF ceramic output capacitor.
