DATASHEET ISL9012 FN9220 Rev 4.00 Dual LDO with Low Noise, Low I , and High PSRR Q December 10, 2015 ISL9012 is a high performance dual LDO capable of Features sourcing 150mA current from Channel 1, and 300mA from Integrates two high performance LDOs Channel 2. The device has a low standby current and - VO1 - 150mA output high-PSRR and is stable with output capacitance of 1F to - VO2 - 300mA output 10F with ESR of up to 200m. Excellent transient response to large current steps The device integrates a Power-On-Reset (POR) function for the VO2 output. The POR delay for VO2 can be externally Excellent load regulation: programmed by connecting a timing capacitor to the CPOR 1% voltage change across full range of load current pin. A reference bypass pin is also provided for connecting a High PSRR: 70dB 1kHz noise-filtering capacitor for low noise and high PSRR Wide input voltage capability: 2.3V to 6.5V applications. Extremely low quiescent current: 45A (both LDOs on) The quiescent current is typically only 45A with both LDOs enabled and active. Separate enable pins control each Low dropout voltage: typically 120mV 150mA individual LDO output. When both enable pins are low, the Low output noise: typically 30V 100A (1.5V) RMS device is in shutdown, typically drawing less than 0.1A. Stable with 1 to10F ceramic capacitors Several combinations of voltage outputs are standard. Separate enable pins for each LDO Output voltage options for each LDO range from 1.5V to 3.3V. Other output voltage options are available on request. POR output, with adjustable delay time indicates when the VO2 output is good Pinout Soft-start to limit input current surge during enable ISL9012 (10 LD 3X3 DFN) Current limit and overheat protection TOP VIEW 1.8% accuracy over all operating conditions Tiny 10 Ld 3x3mm DFN package VIN VO1 1 10 EN1 2 9 VO2 -40C to +85C operating temperature range EN2 POR 3 8 Pin compatible with Micrel MIC2212 CBYP NC 4 7 Pb-free (RoHS compliant) CPOR 5 6 GND Applications PDAs, Cell Phones and Smart Phones Portable Instruments, MP3 Players Handheld Devices including Medical Handhelds FN9220 Rev 4.00 Page 1 of 12 December 10, 2015 ISL9012 Ordering Information PART NUMBER VO1 VOLTAGE VO2 VOLTAGE TEMP RANGE PACKAGE (Notes 1, 2, 3) PART MARKING (V) (V) (C) (Pb-free) PKG.
