Sparkfun Voltage Regulator - Fixed, 3.3V, 150mA (MIC5205)

The MIC5205 is a compact and efficient linear voltage regulator, delivering a stable 3.3V output with an impressive 150mA current capacity. Notable for its ultra-low-noise output and minimal dropout voltage—typically 17mV at light loads and 165mV at full capacity—it maintains exceptional initial accuracy, better than 1%. Designed with battery-powered, handheld devices in mind, it features an enable/shutdown control input compatible with CMOS or TTL, reducing power consumption to nearly zero when not in use.

This voltage regulator is ideal for a variety of applications, particularly in portable electronics where power efficiency and noise reduction are crucial. Its ability to maintain low ground current, even in dropout conditions, significantly extends battery life, making it a preferred choice for devices requiring long-lasting power sources.

Among its unique features, the MIC5205 includes a reference bypass pin to enhance its already superior low-noise performance. Additionally, it provides reversed-battery protection, current limiting, and overtemperature shutdown, ensuring both safety and reliability in various operational environments.
