Product Details
The ADP7185 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 −500 mA of output current. This high output current LDO 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 ADP7185 provides high power supple rejection ratio (PSRR) and low noise, and it achieves excellent line and load transient response with a small 4.7 μF ceramic output capacitor.
The ADP7185 is available in 15 fixed output voltage options. The following voltages are available from stock: −0.5 V, −1.0 V, −1.2 V, −1.5 V, −1.8 V, −2.0 V, −2.5 V, −3.0 V, and −3.3 V.
Additional voltages available by special order are −0.8 V, −0.9 V, −1.3 V, −2.8 V, −4.2 V, and −4.5 V. An adjustable version is also available which allows output voltages that range from −0.5 V to −VIN + 0.5 V with an external feedback divider.
The enable logic feature is capable of interfacing with positive or negative logic levels for maximum flexibility.
The ADP7185 regulator output noise is 4 μV rms independent of the output voltage. The ADP7185 is available in an 8-lead, 2 mm × 2 mm LFCSP, making it not only a very compact solution but also providing excellent thermal performance for applications requiring up to −500 mA of output current in a small, low profile footprint.
