Intersil's high-performance low-dropout ISL805xx regulator is a single-output LDO device capable of delivering up to 1A of output current. The output voltage is programmable from 0.8V to 5.5V.
The sub-micron BiCMOS process provides best-in-class analog performance and overall value. Compared to a bipolar LDO, this CMOS LDO consumes much lower quiescent current as a function of load, which translates into higher efficiency and smaller footprint.
The latest internal compensation enables very fast load transient response and excellent PSRR. The output accuracy of the ISL805xx is �� 1.8% VOUT accuracy at all loads, line and temperature variations (TJ = -40C to + 125C). An external capacitor on the soft-start pin provides adjustable soft-start for the output voltage ramp to control the inrush current. The enable function allows the device to be placed in a low quiescent current shutdown mode.
Typical applications include noise-sensitive instrumentation systems, post-regulation of switching power supplies, industrial systems, medical equipment, telecommunications and networking equipment, servers and hard drives (HD / HDD).
