The MIC2954-03WS TR from Micrel Inc. is an efficient, low-dropout linear voltage regulator designed for applications requiring stable power delivery. It offers a guaranteed output current of 250mA with a very low dropout voltage, typically 40mV at light loads and 375mV at full load, which helps prolong battery life.
Key features include low quiescent current (120µA typical), protection against reversed battery connections, fold-back current limiting, and automotive load dump protection up to +60V. The device also includes an error flag output that warns of a low output voltage, useful for monitoring battery status or as a power-on reset.
This regulator is available in a surface-mount SOT-223-3 package, suitable for automated assembly processes. It operates over a junction temperature range of -40°C to +125°C, making it robust for various environmental conditions. The part number suffix 'TR' indicates it is supplied on tape and reel for high-volume manufacturing.
Applications for the MIC2954-03WS TR include battery-powered equipment, cellular telephones, laptop computers, bar code scanners, and automotive electronics where reliable voltage regulation is critical.
