Overview
Description
The ISL9016A 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. The ISL9016A 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. The ISL9016A also provides output current limit, overheat protection, reverse current protection, as well as excellent load transient response. The ISL9016A is offered in a tiny 1. 6mmx1. 6mm 6 Ld UTDFN package. Output voltage options are available from 1. 2V to 2. 8V. Several combinations of voltage outputs are standard and others may be available upon request.
