The 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 it achieves excellent line and load transient response with a small 4.7 μF ceramic output capacitor.

The ADP7183 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 that 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 ADP7183 regulator output noise is 4 μV rms independent of the output voltage. The ADP7183 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 −300 mA of output current in a small, low profile footprint.

Product Detail

The ADP7183 and ADP7185 evaluation boards demonstrate the functionality of the ADP7183 and ADP7185 series of linear regulators.


Simple device measurements such as line and load regulation, dropout voltage, and ground current can be demonstrated with only a single voltage supply, a voltmeter, an ammeter, and load resistors.


For full details on the ADP7183 and ADP7185 linear regulators, see ADP7183 and ADP7185 data sheet, which must be consulted in conjunction with user guide UG-795 when using these evaluation boards.
