ISL9001 General Description

LDO with Low ISUPPLY, High PSRRISL9001 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.Features• 300mA high performance LDO• Excellent transient response to large current steps• Excellent load regulation: <0.1% voltage change across full range of load current• High PSRR: 90dB @ 1kHz• Wide input voltage capability: 2.3V to 6.5V• Extremely low quiescent current: 25µA• Low dropout voltage: typically 200mV @ 300mA• Low output noise: typically 30µVRMS @ 100µA (1.5V)• Stable with 1µF to 10µF ceramic capacitors• Soft-start to limit input current surge during enable• Current limit and overheat protection• Delayed POR, programmable with external capacitor• ±1.8% accuracy over all operating conditions• Tiny 2mmx3mm 8 Ld DFN package• -40°C to +85°C operating temperature range• Pb-free (RoHS compliant)Applications• PDAs, cell phones and smart phones• Portable instruments, MP3 players• Handheld devices, including medical handhelds
