ISL9014A
Data Sheet March 11, 2008
Dual LDO with Low Noise, Low IQ, and High PSRR
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 are available on request.
