ISL80103IRAJZ

The ISL80103IRAJZ is a low voltage high-current single output high performance LDO Linear Regulator specified for 2 and 3A output current. This LDO operates from the input voltages of 2.2 to 6V and is capable of providing the output voltages of 0.8 to 5.5V on the adjustable VOUT versions. Fixed output voltage options are available in 1.8, 2.5V. For applications that demand in-rush current less than the current limit, an external capacitor on the soft-start pin provides adjustment. A submicron BiCMOS process is utilized for this product family to deliver the best-in-class analog performance and overall value. This CMOS will consume significantly lower quiescent current as a function of load over bipolar LDO, which translates into higher efficiency and the ability to consider packages with smaller footprints. The quiescent current has been modestly compromised to enable a leading class fast load transient response and hence a lower total AC regulation band for an LDO in this category.
