Introduction

AI Translation

The ±√3042 is a high performance low dropout linear regulator featuring ultralow noise and ultrahigh PSRR architecture for powering noise sensitive RF applications. Designed as a precision current reference followed by a high performance voltage buffer, it can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB. The device supplies 200mA at a typical 350mV dropout voltage. Operating quiescent current is nominally 2mA and drops to <<1A in shutdown. Its wide output voltage range (0V to 15V) while maintaining unity - gain operation provides virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage. Additionally, the regulator features programmable current limit, fast start - up capability and programmable power good to indicate output voltage regulation. It is stable with a minimum 4.7µF ceramic output capacitor. Built - in protection includes reverse battery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis. It is available in thermally enhanced 10 - Lead MSOP and 3mm × 3mm DFN packages.
