FN9245.2
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.
Others are available on request. Output voltage options for
each LDO range from 1.2V to 3.6V.
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 - 6.5V
• Extremely low quiescent current: 45μA (both LDOs active)
• Low dropout voltage: typically 200mV @ 300mA
• Low output noise: typically 30μVrms @ 100μA (1.5V)
• Stable with 1-10μF ceramic capacitors
• Separate enable pins for each LDO
• Soft-start to limit input current surge during enable
