ISL9016 is a high performance dual LDO capable of providing

up to 150mA current on each channel. It features a low standby

current and very high PSRR and is stable with output

capacitance of 1μF to 4.7μF with an ESR of up to 200m?.

The device integrates a separate enable function for each

output. The quiescent current is typically 49μA when only one

LDO is enabled and typically 80μA when both LDOs are

enabled. When both LDOs are under shutdown condition, the

drawing current is typically less than 1μA.

ISL9016 provides a wide input voltage range from 1.8V to

6.5V. It also has a high PSRR of 80dB at 1kHz and 45dB at

1MHz. ISL9016 also provides output current limit, overheat

protection, reverse current protection, as well as excellent load

transient response.

ISL9016 is offered in a tiny 1.6mmx1.6mm 6 Ld μTDFN

package. Output voltage options are available from 1.2V to

3.3V. Several combinations of voltage outputs are standard

and others may be available upon request.
