The ISL9008A is a high-performance single low noise, high PSRR LDO that delivers a continuous 150mA of load current. It has a low standby current and is stable with 1μF of MLCC output capacitance with an ESR of up to 200mΩ. The ISL9008A has a high PSRR of 65dB and output noise less than 45μVRMS. When coupled with a no load quiescent current of 46μA (typical), and 0.5μA shutdown current, the ISL9008A is an ideal choice for portable wireless equipment. The ISL9008A comes in several fixed voltage options with ±1.8% output voltage accuracy over-temperature, line and load. Other output voltage options may be available upon request.
The ISL9008A is a high‑performance low‑noise LDO regulator designed for portable wireless equipment. It delivers up to 150 mA continuous load current with very low quiescent and shutdown currents, making it suitable for battery‑powered devices.
Key specifications include a wide 2.3 V‑6.5 V input range, 65 dB PSRR at 1 kHz, output noise under 45 µV, and a typical dropout of 200 mV at 150 mA. The device is offered in 5‑lead SC‑70 or 6‑lead UTDFN packages and operates from –40 °C to +85 °C.
