MIC94345-SYMT-TR

MIC94345-SYMT-TR Description

The MIC94345-SYMT-TR from Microchip Technology is a high-performance, fixed-output linear voltage regulator designed for precision power management in space-constrained applications. Delivering a stable 3.3V output at 500mA, it features an ultra-low dropout voltage of 0.2V (max) at full load, ensuring efficient operation even with tight input voltage margins. Part of the Ripple Blocker™ series, this regulator excels in noise-sensitive environments with an exceptional PSRR of 85dB (100Hz), significantly reducing input ripple and transient interference. Its 250µA quiescent current makes it ideal for battery-powered devices, while RoHS3 compliance and REACH unaffected status align with environmental standards. Packaged in a compact 6-pin TDFN with tape-and-reel (TR) delivery, it suits automated assembly processes.
