Description

ISL9008A is a high performance single low noise, high PSRR LDO that delivers a continuous 150mA of load current. It has a low standby current and is stable with 1μF of MLCC output capacitance with an ESR of up to 200mΩ.

The ISL9008A has a high PSRR of 65dB and output noise less than 45μV_RMS. When coupled with a no load quiescent current of 46μA (typical), and 0.5μA shutdown current, the ISL9008A is an ideal choice for portable wireless equipment.

The ISL9008A comes in several fixed voltage options with ±1.8% output voltage accuracy over-temperature, line and load. Other output voltage options may be available upon request.
