  • Product details

    ADM7171Is a CMOS, low dropout (LDO)Linear regulatorIt operates from a 2.3 V to 6.5 V supply with a maximum output current of 1 A. This high output current LDO is suitable for regulating high-performance analog and mixed-signal circuits from 6 V to 1.2 V. The device uses an advanced, proprietary architecture that provides high power supply rejection, low noise, and excellent line and load transient response with only a small 4.7 μF ceramic output capacitor. The load transient response is typically 1.5 μs (1 mA to 500 mA load step).

    The ADM7171 is available in 17 fixed output voltage options. These options are available in the following voltages: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, and 5.0 V. On special request, the following additional voltage options are available: 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 to regulate the output voltage from 1.2 V to V with an external feedback dividerIN − VDO

    The start-up time can be adjusted via the soft-start pin to control the inrush current. With a 1 nF soft-start capacitor, the typical start-up time is 1.0 ms.

    The ADM7171 regulator outputs a noise voltage of 5 μV rms and is independent of the output voltage. Available in an 8-lead, 3 mm × 3 mm LFCSP package, the ADM7171 is not only very compact, but also has excellent thermal performance for low-profile, small form factor applications requiring up to 1 A output current.
