ISL9016_14 Datasheet, PDF (1/11 Pages) Intersil Corporation – 150mA Dual LDO with Low Noise, High PSRR, and Low IQ

150mA Dual LDO with Low Noise, High PSRR, and Low I_Q
ISL9016
Features
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.
