ISL9005 is a high-performance, low-dropout linear regulator with a maximum output current of 300 mA. It has a low standby current and high-PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200mΩ. The ISL9005 has a high PSRR of 75dB and output noise less than 45µVRMS. When coupled with a no load quiescent current of 50µA (typical), and 0.1µA shutdown current, the ISL9005 is an ideal choice for portable wireless equipment.
The ISL9005 is a high‑performance low‑dropout (LDO) linear regulator capable of delivering up to 300 mA with low standby current and high power‑supply rejection (PSRR). It operates from 2.3 V to 6.5 V input, supports output voltages from 1.5 V to 3.3 V, and includes built‑in current‑limit, thermal‑shutdown, and soft‑start functions.
Typical applications include PDAs, cell phones, MP3 players, handheld medical devices, and other portable wireless equipment. The device is supplied in an 8‑lead DFN package (2 mm × 3 mm) and is RoHS‑compliant.
