Dual LDO with Low Noise, Very High PSRR and Low IQ
ISL9000 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 200m.
Features
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.
• ±1.8% accuracy over all operating conditions
The quiescent current is typically only 42µA with both LDOs
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.
Several combinations of voltage outputs are standard.
Output voltage options for each LDO range are from 1.5V to
3.3V. Other output voltage options may be available upon
request.
• Integrates two 300mA high performance LDOs
• Excellent transient response to large current steps
• Excellent load regulation:
< 0.1% voltage change across full range of load current
• Low output noise: typically 30µVRMS @ 100µA (1.5V)
• Very high PSRR: 90dB @ 1kHz
• 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
• Soft-start and staged turn-on to limit input current surge
during enable
• Current limit and overheat protection

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
4. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
5. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.
