Rev 2.00
November 7, 2014 High Performance 1A LDO
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. Features 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 supplyindependent 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. В±0.2% initial VOUT accuracy 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. Supply-independent 1V enable input threshold The ISL78310 is AEC-Q100 rated. The ISL78310 is rated for
the automotive temperature range (-40В°C to +125В°C).
