ISL80102EVAL2Z開發(fā)板套件編程器的評估板-線性穩(wěn)壓器規(guī)格書PDF中文資料

The ISL80102 and ISL80103 are low voltage, high-current, single

output LDOs specified for 2A and 3A output current, 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 5V on the

adjustable VOUT versions. Fixed output voltage options are

available in 1.8V, 2.5V, 3.3V and 5V. Other custom voltage

options available upon request.

For applications that demand in-rush current less than the

current limit, an external capacitor on the soft-start pin provides

adjustment. The ENABLE feature allows the part to be placed into

a low quiescent current shutdown mode. A sub-micron BiCMOS

process is utilized for this product family to deliver the best in

class analog performance and overall value.

These CMOS (LDOs) will consume significantly lower quiescent

current as a function of load over bipolar LDOs, which translates

into higher efficiency and the ability to consider 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.
