The ADM7172ACPZ-R7 is a CMOS, low dropout linear regulator (LDO) from Analog Devices, designed to operate from a 2.3 V to 6.5 V input range and provide up to 2 A of output current. This high output current capability makes it ideal for regulating power for high-performance analog and mixed-signal circuits.
Key features include ultralow noise of 5 µV rms (independent of output voltage at 100 Hz to 100 kHz) and a high Power Supply Rejection Ratio (PSRR) of 60 dB at 100 kHz. It also boasts a fast transient response of 1.5 μs for a 1 mA to 1.5 A load step, ensuring stable operation under dynamic load conditions. The LDO has a low dropout voltage of 172 mV at a 2 A load when VOUT is 3 V.
Available in fixed output voltage options ranging from 1.3 V to 5.0 V, as well as an adjustable version, the ADM7172ACPZ-R7 is suitable for a wide array of applications. It is designed to be stable with a small 4.7 µF ceramic output capacitor.
The device is housed in an 8-lead, 3 mm × 3 mm LFCSP package, suitable for surface mounting. Its precision enable and adjustable soft-start features offer design flexibility.
