ISL9016

150mA Dual LDO with Low Noise, High PSRR, and Low I<sub>Q</sub>

Product Status: Mass Production

OVERVIEW

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 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.
