ISL9008AIENZ-T IC REG LINEAR 3.3V 150MA SC70-5 Renesas Electronics America Inc

Low Noise LDO with Low IQ, High PSRR

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.

Features

• 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 45µVRMS @ 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
• Current limit and overheat protection
• ±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)

Applications

• PDAs, cell phones and smart phones
• Portable instruments, MP3 players
