ISL9007 is a high performance LDO that delivers a continuous 400mA of load current. It has a low standby current and high PSRR and 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. When coupled with a no load quiescent current of 50µA (typical), and 1µA (max) shutdown current, the ISL9007 is 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 voltage options are available on request.
The ISL9007 is a high‑performance low‑dropout regulator (LDO) that provides a continuous 400 mA output current. It features a very low standby current, excellent transient response, and a high power‑supply‑rejection ratio (PSRR) of 75 dB at 1 kHz. The device is stable with 1 µF‑10 µF ceramic output capacitors and includes shutdown, soft‑start, current‑limit and thermal‑shutdown protections.
Typical applications include PDAs, cell phones, MP3 players, handheld medical devices and other portable wireless equipment. The regulator is offered in a 8‑lead MSOP package with fixed output voltages of 3.3 V, 2.85 V, 2.8 V and 2.5 V, and can be ordered with custom voltage options on request.
