Description

The ISL80102 and ISL80103 are low-voltage, high-current, single-output LDOs specified for 2A and 3A output currents, 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 on the adjustable VOUT versions. Other custom voltage options are available upon request. 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 compromised to enable a leading class fast load transient response, and hence a lower total AC regulation band for an LDO in this category.

  1. Qualification and Reliability data

    May I know how I can obtain some information on any of the product qualification/reliability tests done on ISL80103IRAJZ-TK? i.e. any HTOL/Temperature Cycling/HAST testing etc
