ANALOG DEVICES ADP7183ACPZN3.3-R7 LDO Voltage Regulator, Fixed, -2 to -5.5Vin, -130mV Drop, -3.3V/-0.3A Out, LFCSP-EP-8, -40 to 125 °C

ADP7183ACPZN3.3-R7 is a complementary metal-oxide-semiconductor (CMOS), low dropout (LDO) linear regulator that operates from -2V to -5.5V and provides up to -300mA of output current. This LDO regulator is ideal for regulating high-performance analogue and mixed-signal circuits operating from -0.5V down to -4.5V. Using an advanced proprietary architecture, the ADP7183 provides high PSRR and low noise, achieving excellent line and load transient response with a small 4.7?F ceramic output capacitor. The enable logic feature is capable of interfacing with positive or negative logic levels for maximum flexibility. Applications include regulation for noise-sensitive applications such as analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), precision amplifiers, communications and infrastructure, medical and healthcare, and industrial instrumentation.
