Product Description
Microchip MIC2954-03WS is a high-accuracy voltage regulator designed for power management applications. This device supports input voltages up to 30V and guarantees a 5V output at 250mA with very low dropout voltage, typically 40mV at light loads and 375mV at 250mA. Its low quiescent current of 120μA allows efficient energy use, making it ideal for battery-powered devices.
The MIC2954-03WS features extremely tight load and line regulation with a very low temperature coefficient. It offers robust protection including current limiting, thermal shutdown, and an error flag to indicate low output voltage scenarios. The device also withstands reverse battery conditions (-20V) and transient positive voltages (+60V), ensuring reliability in harsh environments.
Housed in a compact SOT-223 3-pin surface mount package (6.5mm length, 3.5mm width, 1.6mm height), this regulator suits space-constrained circuit designs. Its positive polarity configuration and surface-mount mount type support easy PCB assembly for industrial and commercial electronics.
This voltage regulator finds extensive use in industrial power supplies, automotive electronics, laboratory instruments, and consumer gadgets where precise voltage regulation and energy efficiency are critical. It ensures prolonged battery life and stable system operation under varying loads and input conditions.
Operates with low quiescent current for prolonged energy efficiency. High precision is ensured by tight line and load regulation. Designed to protect against reverse polarity and voltage transients. Error flag feature provides system fault signaling.
Compact surface-mount SOT-223 package suits modern electronics design. Capable of thermal and current limiting for safety. Wide operating temperature range up to 125°C enhances durability. Ideal for industrial, automotive, consumer, and embedded electronics.
