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 45μV_RMS. 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.

• High performance LDO with 150mA continuous output
• Excellent transient response to large current steps
• Excellent load regulation: <0.1% voltage change across full range of load current
• High PSRR: 65dB @ 1kHz
• Wide input voltage capability: 2.3V to 6.5V
• Very low quiescent current: 46μA
• Low dropout voltage: typically 200mV @ 150mA
• Low output noise: typically 45μV_RMS @ 100μA (1.5V)
• Stable with 1μF to 4.7μF ceramic capacitors
• Shutdown pin turns off LDO with 1μA (max) standby current
• Soft-start limits input current surge during enable

• ±1.8% accuracy over all operating conditions
• 5 Ld SC-70 package or 6 Ld μTDFN package
• -40°C to +85°C operating temperature range
• Pb-free (RoHS compliant)

• PDAs, cell phones and smart phones
• Portable instruments, MP3 players
• Handheld devices including medical handhelds
