ISL9011A is a high performance dual LDO from ISL, with two output currents of 150mA and 300mA, supporting 1.5V to 3.3V multiple output voltages, static current as low as 45µA, with good transient response, low dropout voltage, high PSRR and other characteristics.
The ISL9011A is a high‑performance dual low‑dropout regulator that provides two independent LDO channels (VO1 and VO2). Channel 1 can source up to 150 mA, while channel 2 can source up to 300 mA, both with low noise and high PSRR.
The device operates from a 2.3 V to 6.5 V supply, features a typical quiescent current of 45 µA, and includes separate enable pins, soft‑start, current‑limit and over‑heat protection. It is supplied in a 3 × 3 mm DFN package and is RoHS‑compliant.
| VO1 output current | 150 mA |
|---|---|
| VO2 output current | 300 mA |
| Quiescent current (both LDOs active) | 45 µA |
| Low dropout voltage @ 150 mA | 120 mV |
| High PSRR | 70 dB @ 1 kHz |
| Input voltage range | 2.3 V to 6.5 V |
| Operating temperature range | -40 °C to +85 °C |
| Low output noise | 30 µV RMS @ 100 µA (1.5 V) |
The typical quiescent current is 45 µA when both LDO channels are enabled.
VO1 can deliver up to 150 mA and VO2 up to 300 mA.
It operates from 2.3 V to 6.5 V.
The dropout voltage is typically about 120 mV at 150 mA load.
