Intel(Intersil) ISL9012 Data Sheet
Summary
The ISL9012 is a high-performance dual Low Dropout Regulator (LDO) designed for powering critical circuits in demanding portable electronics. It provides two independently controllable, highly stable voltage outputs while maintaining an extremely low quiescent current (45µA). This datasheet details the device’s comprehensive technical specifications, including advanced features like high PSRR, Power-On-Reset (POR), and wide input/output voltage options. Ideal for engineers developing smart phones, PDAs, or medical handheld devices that require both reliable power regulation and ultra-low power consumption in a compact footprint.

Frequently Asked Questions
What is the operating temperature range?
The device operates in a -40°C to +85°C temperature range.
How stable are the LDO outputs regarding input voltage swings or load changes?
They offer excellent transient response, excellent load regulation (1% change), and high PSRR of 70dB @ 1kHz.
What is the typical quiescent current draw?
The quiescent current typically remains only 45µA when both LDOs are enabled and active.
Are there separate controls for each power output?
Yes, the device features separate enable pins (EN1 and EN2) to control each individual LDO output.
