6.5 V, 2 A, Ultralow Noise, High PSRR, Fast Transient Response CMOS LDO Known Good Die ADM7172-KGD FEATURES GENERAL DESCRIPTION Input voltage range: 2.3 V to 6.5 V The ADM7172-KGD is a CMOS, low dropout linear regulator Maximum load current: 2 A (LDO) that operates from 2.3 V to 6.5 V and provides up to 2 A Low noise: 5 V rms independent of output voltage at of output current. This high output current LDO is ideal for 100 Hz to 100 kHz regulation of high performance analog and mixed-signal circuits Fast transient response: 1.5 s for 1 mA to 1.5 A load step operating from 6 V down to 1.2 V rails. Using an advanced 60 dB PSRR at 100 kHz proprietary architecture, the device provides high power supply Low dropout voltage: 172 mV at 2 A load, V = 3 V OUT rejection and low noise and achieves excellent line and load Initial accuracy: 0.5% (minimum), +1% (maximum) transient response with just a small 4.7 F ceramic output Accuracy over line, load, and temperature: 1.5% capacitor. Load transient response is typically 1.5 s for a 1 mA Quiescent current, I = 0.7 mA with no load GND to 1.5 A load step. Low shutdown current: 0.25 A at V = 5 V IN The ADM7172-KGD is available in a 4.2 V fixed output voltage Stable with small 4.7 F ceramic output capacitor option. Additional voltages that are available by special order are Adjustable and fixed output voltage options: 1.2 V to 5.0 V 1.3 V, 1.5 V, 1.8 V, 1.85 V, 2.0 V, 2.2 V, 2.5 V, 2.7 V, 2.75 V, 2.8 V, Adjustable output from 1.2 V to V V IN DO 2.85 V, 3.0 V, 3.8 V, 3.3 V, 4.2 V, 4.6 V, 5.0 V, and an adjustable Precision enable output option. Adjustable soft start Inrush current can be controlled by adjusting the start-up time APPLICATIONS via the soft start pin. The typical start-up time with a 1 nF soft Regulation to noise sensitive applications: analog-to-digital start capacitor is 1.0 ms. converter (ADC) and digital-to-analog converter (DAC) The ADM7172-KGD regulator output noise is 5 V rms, circuits, precision amplifiers, phase-locked loops (PLLs)/ independent of the output voltage. voltage controlled oscillators (VCOs), and clocking ICs Additional application and technical information can be found Communications and infrastructure in the ADM7172 data sheet.
