Renesas Electronics Corporation Voltage Regulators - Linear ISL9008AIENZ-T

The ISL9008AIENZ-T is a low dropout linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output of 3.3V with a maximum continuous load current of 150mA. It operates within a wide input voltage range of 2.3V to 6.5V and features a low quiescent current of 46µA, making it suitable for battery-powered applications. The device exhibits a high power supply rejection ratio (PSRR) of 65dB at 1kHz and low output noise of less than 45µVRMS, which is beneficial for sensitive electronic circuits. It is stable with ceramic output capacitors ranging from 1µF to 4.7µF and includes protection features such as current limiting and thermal shutdown. The ISL9008AIENZ-T is available in a compact 5-lead SC-70 package and operates over a temperature range of -40°C to +85°C. This regulator is particularly well-suited for portable devices, including PDAs, smartphones, and handheld medical instruments.
