DATASHEET ISL9007 FN9218 Rev 3.1 High Current LDO with Low I and High PSRR Q Jul 29, 2021 ISL9007 is a high performance LDO that delivers a continuous Features 400mA of load current. It has a low standby current and High performance LDO with 400mA continuous output high PSRR and is stable with output capacitance of 1F to 10F with an ESR of up to 200m . Excellent transient response to large current steps The ISL9007 has a very high PSRR of 75dB and output noise Excellent load regulation: <0.1% voltage change across full less than 30V . When coupled with a no load quiescent range of load current RMS current of 50A (typical), and 1A (max) shutdown current, the Very high PSRR: 75dB 1kHz ISL9007 is an ideal choice for portable wireless equipment. Wide input voltage capability: 2.3V to 6.5V The ISL9007 comes in fixed voltage options of 3.3V, 2.85V, Very low quiescent current: 50A 2.8V, and 2.5V with 1.8% output voltage accuracy Low dropout voltage: typically 200mV 400mA over-temperature, line and load. Other output voltage options may be available upon request. Low output noise: typically 30V 100A (2.5V) RMS Stable with 1F to 10F ceramic capacitors Shutdown pin turns off LDO for 1A (max) standby current Soft-start to limit input current surge during enable Current limit and overheat protection 1.8% accuracy over all operating conditions 8 Ld MSOP package -40C to +85C operating temperature range Pb-free (RoHS compliant) Applications PDAs, Cell Phones and Smart Phones Portable Instruments, MP3 Players Handheld Devices, including Medical Handhelds VIN VO VIN UVLO ISL9007 1 8 VIN (3.0V TO 6.5V) VIN VO VOUT SHORT CIRCUIT, 7 CONTROL VIN THERMAL PROTECTION, OFF LOGIC SOFT-START 6 5 SHUTDOWN SD GND ON C1 C2 SD + - C , C : 1F X5R CERAMIC CAPACITOR 1 2 BANDGAP AND TEMPERATURE SENSOR GND FIGURE 1.
