Dual LDO with Low Noise, Low IQ, and High PSRR

ISL9012 is a high performance dual LDO capable of sourcing 150mA current from channel 1 and 300mA from channel 2. The device has a low standby current and highPSRR and is stable with output capacitance of 1μF to 10μF with ESR of up to 200mΩ.

Features

• Integrates two high performance LDOs
- VO1 - 150mA output
- VO2 - 300mA output
• Excellent transient response to large current steps
• Excellent load regulation:
• <1% voltage change across full range of load current
• High PSRR: 70dB @ 1kHz
• Wide input voltage capability: 2.3V - 6.5V
• Extremely low quiescent current: 45μA (both LDOs on)
• Low dropout voltage: typically 120mV @ 150mA
• Low output noise: typically 30μVrms @ 100μA(1.5V)
• Stable with 1-10μF ceramic capacitors
• Separate enable pins for each LDO
• POR output, with adjustable delay time indicates when the VO2 output is good
• Soft-start to limit input current surge during enable
• Current limit and overheat protection
• ±1.8% accuracy over all operating conditions
• Tiny 10 Ld 3x3mm DFN package
• -40°C to +85°C operating temperature range
• Pin compatible with Micrel MIC2212
• Pb-free plus anneal available (RoHS compliant)

Applications

• PDAs, Cell Phones and Smart Phones
• Portable Instruments, MP3 Players
• Handheld Devices including Medical Handhelds
