ISL9001 is a high-performance low dropout linear regulator capable of sourcing 300mA current. It has a low standby current and high PSRR and is stable with an output capacitance of 1µF to 10µF with an ESR of up to 200mΩ. The ISL9001 has a very high PSRR of 90dB and outputs noise less than 30µVRMS. A reference bypass pin allows connection of a noise-filtering capacitor for low-noise and high-PSRR applications. When coupled with a no-load quiescent current of 25µA (typical) and 0.1µA shutdown current, the ISL9001 is an ideal choice for portable wireless equipment. The ISL9001 provides a power-good signal with delay time programmable with an external capacitor. Several different fixed voltage outputs are standard. Output voltage options for each LDO range are from 1.5V to 3.3V. Other output voltage options may be available upon request.
The ISL9001 is a high‑performance LDO regulator designed for portable wireless equipment. It delivers up to 300 mA with a typical quiescent current of 25 µA, a low dropout voltage of about 200 mV at full load, and a PSRR of 90 dB at 1 kHz. The device supports fixed output voltages from 1.5 V to 3.3 V and can be programmed via external capacitors for power‑good signaling and soft‑start.
Typical applications include PDAs, cell phones, MP3 players, handheld medical devices and other battery‑powered electronics. The DFN‑8 package and RoHS‑compliant, Pb‑free construction simplify board layout and meet environmental standards.
