ISL9011
FN9219.5
Dual LDO with Low Noise, Low I Q and
High PSRR
ISL9011 is a high performance dual LDO capable of
sourcing 150mA current from Channel 1 and 300mA from
Channel 2. The device has a low standby current and
high-PSRR and is stable with output capacitance of 1μF to
10μF with ESR of up to 200m Ω .
A reference bypass pin allows an external capacitor for
adjusting a noise filter for low noise and high PSRR
applications.
The quiescent current is typically only 45μA 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 high performance LDOs
- VO1 - 150mA output
- VO2 - 300mA output
? Excellent transient response to large current steps
? Excellent load regulation: <1% voltage change across full
range of load current
? High PSRR: 70dB @ 1kHz
? Wide input voltage capability: 2.3V to 6.5V
? Extremely low quiescent current: 45μA (both LDOs active)
? Low dropout voltage: typically 120mV @ 150mA
? Low output noise: typically 30μV RMS @ 100μA (1.5V)
? Stable with 1μF to10μF ceramic capacitors
? Separate enable pins for each LDO
? Soft-start to limit input current surge during enable
