ISL9014A is a high performance dual LDO from ISL company, which can provide 300mA current. The output voltage range is from 1.5V to 3.3V. It features low standby current, high PSRR, good load regulation characteristics and extremely low output noise, and is suitable for applications requiring low standby current, low output noise and high PSRR.
The ISL9014A dual LDO provides two independent low‑dropout regulators with output currents up to 300 mA. It features ultra‑low quiescent current, excellent transient response, and high power‑supply rejection (70 dB at 1 kHz). Separate enable pins allow independent control of each regulator.
The device operates from a 2.3 V to 6.5 V input range and is specified for –40 °C to +85 °C ambient temperature. It is supplied in a 3 × 3 mm DFN package and includes a reference bypass pin for noise‑filter tuning.
| Output current per LDO | 300 mA |
|---|---|
| Quiescent current (both LDOs active) | 45 µA |
| Dropout voltage (typical at 300 mA) | 200 mV |
| Output noise (typical) | 30 µV rms |
| PSRR (1 kHz) | 70 dB |
| Input voltage range | 2.3 V to 6.5 V |
The typical quiescent current is only 45 µA with both LDOs enabled.
It has separate enable pins (EN1 and EN2) for each LDO.
Each LDO can continuously source up to 300 mA.
In shutdown the device draws less than 0.1 µA.
