The ISL78310 is a low dropout voltage, high-current, single output LDO specified for 1A output current. This part operates from input voltages down to 2. 2V and up to 6V. The part offers fixed and external resistor adjustable output voltages from 0. 8V to 5V. Custom voltage options are available upon request. For applications that desire to set the in-rush current to less than the current limit of the part, or for applications that require turn-on time control, an external capacitor can be placed on the soft-start pin for maximum control. A supply-independent ENABLE signal allows the part to be placed into a low quiescent current shutdown mode. Sub-micron CMOS process is used for this product family to deliver best-in-class analog performance and overall value. This CMOS LDO consumes significant lower quiescent (ground pin) current as a function of load over bipolar LDOs, which translates into higher efficiency and packages with smaller footprints. Quiescent current is optimized to achieve a very fast load transient response. The ISL78310 is AEC-Q100 rated. The ISL78310 is rated for the automotive temperature range (-40°C to +125°C).
