ISL80101EVAL2Z开发板套件编程器的评估板-线性稳压器规格书PDF中文资料

The ISL80101-ADJ is a low voltage, high current, single output

LDO specified at 1A output current. This LDO operates from

input voltages from 2.2V to 6V, and is capable of providing

output voltages from 0.8V to 5V. The ISL80101-ADJ features

an adjustable output. For the fixed output version of the

ISL80101-ADJ, please refer to the ISL80101 datasheet.

A submicron BiCMOS process is utilized for this product family

to deliver the best in class analog performance and overall

value. This CMOS LDO will consume significantly lower

quiescent current as a function of load compared to bipolar

LDOs, which translates into higher efficiency and packages

with smaller footprints. State of the art internal compensation

achieves a very fast load transient response. An external

capacitor on the soft-start pin provides an adjustable

soft-starting ramp. The ENABLE feature allows the part to be

placed into a low quiescent current shutdown mode. A

Power-good logic output signals a fault condition.
