The Intersil ISL80101 ia a low-voltage, high-current, single output LDO specified for 1A output current. This part operates from input voltages of 2.2V to 6V and is capable of providing output voltages of 0.8V to 5V on the adjustable VOUT versions. Fixed output voltage options available in 0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V. Other custom voltage options available upon request.
For applications that demand in-rush current less than current limit or a longer delay for a valid VOUT, an external capacitor on the soft-start pin provides adjustment. A supply independent ENABLE signal allows the part to be placed into a low quiescent current shutdown mode. Sub-micron CMOS process is utilized for this product family to deliver best in class analog performance and overall value.
This CMOS LDO will consume significantly lower quiescent current as a function of load over bipolar LDOs, which translates into higher efficiency and the ability to consider packages with smaller footprints. Quiescent current is modestly compromised to enable leading class fast load transient response and hence total AC regulation band for an LDO in this category.
