ISL80103 Datasheet High Performance 2a And 3a Linear Regulators

Manufacturer: Renesas

Overview: ISL80102, ISL80103 High Performance 2A and 3A Linear Regulators The ISL80102 and ISL80103 are low voltage, high-current, single output LDOs specified for 2A and 3A output current, respectively. These LDOs operate from the input voltages of 2.2V to 6V and are capable of providing the output voltages of 0.8V to 5.5V. An external capacitor on the soft-start pin provides adjustment for applications that demand inrush current less than the current limit. The ENABLE feature allows the part to be placed into a low quiescent current shutdown mode. A submicron BiCMOS process is used for this product family to deliver best-in-class analog performance and overall value. These CMOS (LDOs) consume significantly lower quiescent current as a function of load over bipolar LDOs, so they are more efficient and allow packages with smaller footprints. The quiescent current has been modestly promised to enable a leading class fast load transient response, and hence a lower total AC regulation band for an LDO in this category.
