1 / 11 page 1 ® FN6438.0 ISL9014A Dual LDO with Low Noise, Low IQ, and High PSRR ISL9014A is a high performance dual LDO capable of sourcing 300mA current from both outputs. The device has a low standby current and high-PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200m Ω. A reference bypass pin allows an external capacitor for adjusting a noise filter for low noise and high PSRR applications. The quiescent current is typically only 45µA with both LDOs enabled and active. Separate enable pins control each individual LDO output. When both enable pins are low, the device is in shutdown, typically drawing less than 0.1µA. Several combinations of voltage outputs are standard. Others are available on request. Output voltage options for each LDO range from 1.2V to 3.6V. Pinout ISL9014A (10 LD 3x3 DFN) TOP VIEW Features • Integrates two high performance LDOs - VO1 - 300mA 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 to 6.5V • Extremely low quiescent current: 45µA (both LDOs active) • Low dropout voltage: typically 200mV @ 300mA • Low output noise: typically 30µVRMS @ 100µA (1.5V) • Stable with 1µF to 10µF ceramic capacitors • Separate enable pins for each LDO • Soft-start to limit input current surge during enable • Current limit and overheat protection • ±1.8% accuracy over all operating conditions • Tiny 10 Ld 3mmx3mm DFN package • -40°C to +85°C operating temperature range • Pin compatible with Micrel MIC2211 • Pb-free plus anneal available (RoHS compliant) Applications • PDAs, Cell Phones and Smart Phones • Portable Instruments, MP3 Players • Handheld Devices including Medical Handhelds VIN EN1 EN2 CBYP NC VO1 VO2 NC NC GND 2 3 4 1 5 9 8 7 10 6 Data Sheet January 30, 2007 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
