ISL9014 is a high performance dual LDO chip launched by ISL, supporting 300mA output current, output voltage can be selected from 1.5V-3.3V, and has low noise, low standby current and high PSRR features.
The ISL9014 integrates two low‑noise LDOs capable of delivering up to 300 mA from each output. It features low standby current (45 µA), high PSRR (70 dB @ 1 kHz), and a soft‑start circuit to limit in‑rush current.
The device operates from 2.3 V to 6.5 V supply voltage, supports output voltages from 1.5 V to 3.3 V, and is supplied in a 10‑lead DFN package. It includes separate enable pins, over‑temperature shutdown, and is RoHS‑compliant.
| Continuous Output Current | 300 mA per LDO |
|---|---|
| Quiescent Current (both LDOs active) | 45 µA |
| Dropout Voltage (typical) | 200 mV @ 300 mA |
| PSRR (1 kHz) | 70 dB |
| Output Noise (100 µA load, 1.5 V) | 30 µV RMS |
| Package | 10‑lead DFN 3 mm × 3 mm |
The quiescent current is typically only 45 µA with both LDOs active.
Each LDO can be set to output voltages ranging from 1.5 V to 3.3 V.
Each LDO can supply up to 300 mA continuously.
The device draws less than 0.1 µA in shutdown.
