ISL80103IRAJZ-TK

ISL80103IRAJZ-TK is a ISL80103 high performance 2A and 3A linear regulator. It is a low voltage, high-current, single output LDOs specified for 2A and 3A output current, respectively. This LDO 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 analogue performance and overall value. This CMOS (LDOs) consume significantly lower quiescent current as a function of load over bipolar LDOs, so this is more efficient and allow packages with smaller footprints. Application includes servers, telecommunications and networking, medical equipment, instrumentation systems, routers and switchers.
