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 200m Ω .
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.
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.
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.
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
? Low output noise: typically 30μV RMS @ 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
? 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
