High Performance 1A LDO
ISL78310
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).
