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 46¬µA, 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 45¬µVRMS, which is beneficial for sensitive electronic circuits. It is stable with ceramic output capacitors ranging from 1¬µF to 4.7¬µF 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¬8C to +85¬8C. This regulator is particularly well-suited for portable devices, including PDAs, smartphones, and handheld medical instruments.
