ISL9014
March 11, 2008
FN9245.3
Dual LDO with Low Noise, Low I
Q
and
High PSRR
ISL9014 is a high performance dual LDO capable of
sourcing 300mA current from both outputs. 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 200mΩ.
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 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 from 1.5V to
3.3V. Other output voltage options may be available upon
request.
Features
• Integrates two high performance LDOs
- VO1 - 300mA 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 200mV @ 300mA
• Low output noise: typically 30µV
RMS
@ 100µA (1.5V)
• Stable with 1µF to 10µF ceramic capacitors
• Separate enable pins for each LDO
• Soft-start to limit input current surge during enable
• Current limit and overheat protection
