The ISL9007 is a high performance low dropout regulator from Infineon Technologies, with a maximum output current of 400mA. The device has low quiescent current and high PSRR, and it is stable with output capacitance of 1µF to 10µF with an ESR of up to 200mΩ. The ISL9007 has a very high PSRR of 75dB and output noise less than 30µVRMS. The device has a no load quiescent current of 50µA (typical), and a 1µA (max) shutdown current, making it an ideal choice for portable wireless equipment. The ISL9007 comes in fixed voltage options of 3.3V, 2.85V, 2.8V, and 2.5V with ±1.8% output voltage accuracy over-temperature, line and load. Other output voltage options may be available upon request.
The ISL9007 is a high‑current LDO regulator delivering up to 400 mA continuous load current. It features a low dropout voltage of about 200 mV at 400 mA, very low standby current (≈50 pA), and a high power‑supply‑rejection ratio of 75 dB at 1 kHz. Fixed output voltage options include 3.3 V, 2.85 V, 2.8 V and 2.5 V.
The device is supplied in an 8‑lead MSOP package with pin functions for output, ground, shutdown, and input. It includes integrated current‑limit, thermal‑shutdown, and soft‑start circuitry. Typical applications are portable wireless equipment, handheld devices, and other low‑power battery‑operated systems.
