The ADM7172 is a CMOS, low dropout linear regulator (LDO) that operates from 2.3 V to 6.5 V and provides up to 2 A of output current. This high output current LDO is ideal for regulation of high performance analog and mixed-signal circuits operating from 6 V down to 1.2 V rails. Using an advanced proprietary architecture, the device provides high power supply rejection and low noise, and achieves excellent line and load transient response with just a small 4.7 µF ceramic output capacitor. Load transient response is typically 1.5 μs for a 1 mA to 1.5 A load step.The ADM7172 is available in 17 fixed output voltage options. The following voltages are available from stock: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, and 5.0 V. Additional voltages that are available by special order are: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.7 V, 2.75 V, 2.8 V, 2.85 V, 3.8 V, and 4.6 V. An adjustable version is also available that allows output voltages that range from 1.2 V to VIN − VDO with an external feedback divider.Inrush current can be controlled by adjusting the start-up time via the soft start pin. The typical start-up time with a 1 nF soft start capacitor is 1.0 ms.The ADM7172 regulator output noise is 5 μV rms, independent of the output voltage. The ADM7172 is available in an 8-lead, 3 mm × 3 mm LFCSP, making it not only a very compact solution, but also providing excellent thermal performance for
