DATASHEET ISL9016 FN6832 Rev 1.00 150mA Dual LDO with Low Noise, High PSRR, and Low I Q May 16, 2011 ISL9016 is a high performance dual LDO capable of providing Features up to 150mA current on each channel. It features a low standby Dual Integrated 150mA High Performance LDOs current and very high PSRR and is stable with output capacitance of 1F to 4.7F with an ESR of up to 200m. High PSRR: 80dB 1kHz and 45dB 1MHz The device integrates a separate enable function for each Reverse Current Protection output. The quiescent current is typically 49A when only one Low Quiescent Current LDO is enabled and typically 80A when both LDOs are - 49A (Single LDO Enabled)/80A (Dual LDOs Enabled) enabled. When both LDOs are under shutdown condition, the drawing current is typically less than 1A. Excellent Load Transient Response Typically 0.8% Output Voltage Accuracy 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 Low Output Noise: Typically 25V RMS 1MHz. ISL9016 also provides output current limit, overheat Wide Input Voltage Capability: 1.8V to 6.5V protection, reverse current protection, as well as excellent load transient response. Low Dropout Voltage: Typically 120mV 150mA Separate Enable Control for each LDO ISL9016 is offered in a tiny 1.6mmx1.6mm 6 Ld TDFN package. Output voltage options are available from 1.2V to Stable with 1F to 4.7F Ceramic Output Capacitors 3.3V. Several combinations of voltage outputs are standard Soft-start to Limit Input Current Surge During Enable and others may be available upon request.
