ADP7182ACPZN-2.5R7

ADP7182ACPZN-2.5R7 is a CMOS, low dropout (LDO) linear regulator that operates from -2.7V to -28V and provides up to -200mA of output current. This high input voltage LDO is ideal for the regulation of high-performance analogue and mixed-signal circuits operating from -27V down to -1.2V rails. Using an advanced proprietary architecture, it provides high power supply rejection and low noise and achieves excellent line and load transient response with a small 2.2μF ceramic output capacitor. The ADP7182 regulator output noise is 18μV rms independent of the output voltage. The enable logic is capable of interfacing with positive or negative logic levels for maximum flexibility. Application includes regulation to noise-sensitive applications, analogue-to-digital converter (ADC) and digital-to-analogue converter (DAC) circuits, precision amplifiers, communications and infrastructure, medical and healthcare, industrial and instrumentation.
