It has a low standby current and very high PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200m. Features The device integrates an individual Power-On-Reset (POR) function for each output. The POR delay for VO2 can be externally programmed by connecting a timing capacitor to the CPOR pin. The POR delay for VO1 is internally fixed at approximately 2ms. A reference bypass pin is also provided for connecting a noise filtering capacitor for low noise and high-PSRR applications. • ±1.8% accuracy over all operating conditions The quiescent current is typically only 42µA 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. Output voltage options for each LDO range are from 1.5V to 3.3V. Other output voltage options may be available upon request. • Integrates two 300mA high performance LDOs • Excellent transient response to large current steps • Excellent load regulation: < 0.1% voltage change across full range of load current • Low output noise: typically 30µVRMS @ 100µA (1.5V) • Very high PSRR: 90dB @ 1kHz • Extremely low quiescent current: 42µA (both LDOs active) • Wide input voltage capability: 2.3V to 6.5V • Low dropout voltage: typically 200mV @ 300mA • Stable with 1µF to 10µF ceramic capacitors • Separate enable and POR pins for each LDO • Soft-start and staged turn-on to limit input current surge during enable • Current limit and overheat protection Pinout • Tiny 10 Ld 3mmx3mm DFN package ISL9000 (10 LD 3X3 DFN) TOP VIEW • -40°C to +85°C operating temperature range • Pb-free (RoHS compliant) VIN 1 10 VO1 Applications EN1 2 9 VO2 • PDAs, Cell Phones and Smart Phones EN2 3 8 POR2 • Portable Instruments, MP3 Players CBYP 4 7 POR1 • Handheld Devices including Medical Handhelds CPOR 5 6 GND FN9217 Rev 4.00 March 11, 2008 Page 1 of 11 ISL9000 Ordering Information PART NUMBER (Notes 1, 2, 3) PART MARKING VO1 VOLTAGE (V) VO2 VOLTAGE (V) TEMP RANGE (°C) PACKAGE (Pb-Free) PKG DWG. # ISL9000IRNNZ DCGA 3.3 3.3 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRNJZ DAAA 3.3 2.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRNFZ DBAA 3.3 2.5 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRNCZ DABH 3.3 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRMNZ DCHA 3.0 3.3 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRMMZ DSAA 3.0 3.0 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRMGZ DCJA 3.0 2.7 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRLLZ DRAA 2.9 2.9 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRKNZ DABF 2.85 3.3 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRKKZ DCAA 2.85 2.85 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRKJZ DDAA 2.85 2.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRKFZ DEAA 2.85 2.5 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRKPZ DABG 2.85 1.85 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRKCZ DHAA 2.85 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRJNZ DCKA 2.8 3.3 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRJMZ DPAA 2.8 3.0 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRJRZ DNAA 2.8 2.6 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRJCZ DMAA 2.8 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRJBZ DFAA 2.8 1.5 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRGPZ DABE 2.7 1.85 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRGCZ DLAA 2.7 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRFJZ DGAA 2.5 2.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRFDZ DCLA 2.5 2.0 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRFCZ DCMA 2.5 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRPLZ DKAA 1.85 2.9 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRPPZ DABJ 1.85 1.85 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRCJZ DCNA 1.8 2.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRCCZ DCPA 1.8 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRBLZ DABD 1.5 2.9 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRBJZ DJAA 1.5 2.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRBCZ DABC 1.5 1.8 -40 to +85 10 Ld 3x3 DFN L10.3x3C ISL9000IRBBZ DABB 1.5 1.5 -40 to +85 10 Ld 3x3 DFN L10.3x3C NOTES: 1.
