ISL80112EVAL1Z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 ISL80111, ISL80112, and ISL80113 are ultra low dropout

LDOs providing the optimum balance between performance, size

and power consumption in size constrained designs for data

communication, computing, storage and medical applications.

These LDOs are specified for 1A, 2A and 3A of output current and

are optimized for low voltage conversions.Operating with a VIN of

1V to 3.6V and with a legacy 3.3V to 5V on the BIAS, the VOUT is

adjustable from 0.8V to 3.3V. With a VIN PSRR greater than 40dB

at 100kHz makes these LDOs an ideal choice in noise sensitive

applications. The guaranteed ±1.6 VOUT accuracy overall

conditions lends these parts to suppling an accurate voltage to

the latest low voltage digital ICs.

An enable input allows the part to be placed into a low quiescent

current shutdown mode. A submicron CMOS process is utilized for

this product family to deliver best-in-class analog performance

and overall value for applications in need of input voltage

conversions typically below 2.5V. It also has the superior load

transient regulation unique to a NMOS power stage. These LDOs

consume significantly lower quiescent current as a function of

load compared to bipolar LDOs.
