GENERAL DESCRIPTION
The ADP7182 is a CMOS, low dropout (LDO) linear
regulator that operates from −2.7 V to −28 V and provides up to −200 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from −27 V down to −1.2 V 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 2.2 μF ceramic output capacitor.
The ADP7182 is available in fixed output voltage and an adjustable version that allows the output voltage to ...
