Product Overview

The ADM7172ACPZ-R7 is an ultralow noise high PSRR fast transient response CMOS low dropout Linear Regulator that operates from 2.3 to 6.5V and provides up to 2A of output current. This high output current LDO is ideal for regulation of high performance analog and mixed-signal circuits operating from 6 down to 1.2V 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 4.7µF ceramic output capacitor. Load transient response is typically 1.5µs for a 1mA to 1.5A load step. An adjustable version is also available that allows output voltages that range from 1.2V 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 1nF soft start capacitor is 1ms. The ADM7172 regulator output noise is 5µVrms, independent of the output voltage.
