1 / 15 page 1 High Performance 2A and 3A Linear Regulators ISL80102, ISL80103 The ISL80102 and ISL80103 are low voltage, high-current, single output LDOs specified for 2A and 3A output current, respectively. These LDOs operate from input voltages of 2.2V to 6V and are capable of providing output voltages of 0.8V to 5V on the adjustable VOUT versions. Fixed output voltage options are available in 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 the current limit, an external capacitor on the soft start pin provides adjustment. The ENABLE feature allows the part to be placed into a low quiescent current shutdown mode. A sub-micron BiCMOS process is utilized for this product family to deliver the best in class analog performance and overall value. These CMOS LDOs 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 a leading class fast load transient response, and hence a lower total AC regulation band for an LDO in this category.
