150mA Dual LDO with Low Noise, High
PSRR, and Low I

ISL9016 is a high performance dual LDO capable o f providing
up to 150mA current on each channel. It features a low
standby current and very high PSRR and is sta ble with output
capacitance of 1µF to 4.7µF with an ESR of up to 200mΩ.

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.
