Dual LDO with Low Noise, Very High PSRR and Low I  
Q
ISL9000A  
ISL9000A is a high performance dual LDO capable of sourcing  
300mA current from each output. It has a low standby current  
and very high PSRR and is stable with output capacitance of  
1µF to 10µF with ESR of up to 200mΩ.  
Features  
• Integrates two 300mA high performance LDOs  
• Excellent transient response to large current steps  
• ±1.8% accuracy over all operating conditions  
• Excellent load regulation: < 0.1% voltage change across full  
range of load current  
The device integrates an individual Power-On-Reset (POR)  
function for each output. The POR delay for VO2 can be  
externally programmed by connecting a timing capacitor to the  
CPOR pin. The POR delay for VO1 is internally fixed at  
approximately 2ms. A reference bypass pin is also provided for  
connecting a noise filtering capacitor for low noise and high-  
PSRR applications.  
• Low output noise: typically 30µV  
• Very high PSRR: 90dB @ 1kHz  
@ 100µA (1.5V)  
RMS  
• Extremely low quiescent current: 42µA (both LDOs active)  
• Wide input voltage capability: 2.3V to 6.5V  
• Low dropout voltage: typically 200mV @ 300mA  
• Stable with 1µF to 10µF ceramic capacitors  
• Separate enable and POR pins for each LDO  
The quiescent current is typically only 42µA with both LDO’s  
enabled and active. Separate enable pins control each  
individual LDO output. When both enable pins are low, the  
device is in shutdown, typically drawing less than 0.1µA.  
• Soft-start and staged turn-on to limit input current surge  
during enable  
Several combinations of voltage outputs are standard. Output  
voltage options for each LDO range from 1.5V to 3.3V. Other  
output voltage options may be available upon request.  
• Current limit and overheat protection  
• Tiny 10 Ld 3mmx3mm DFN package  
• -40°C to +85°C operating temperature range  
• Pb-free (RoHS compliant)  
Applications  
• PDAs, Cell Phones and Smart Phones  
• Portable Instruments, MP3 Players  
• Handheld Devices including Medical Handheld
