MIC5253-3.3BC5 Description

Short technical summary and product information.

The MIC5253-3.3BC5 from Micrel Inc. is an efficient CMOS voltage regulator optimized for ultra-low-noise applications. It provides a 100mA continuous output current with a low dropout voltage of 165mV at 100mA. The regulator offers 1.5% initial accuracy and operates over an input voltage range of 2.7V to 5.5V.

This device is ideal for RF applications requiring a clean voltage source, featuring ultra-low output noise of 30 µV(rms). A noise bypass pin is available for further noise reduction. The MIC5253-3.3BC5 is designed for handheld and battery-powered devices, incorporating a TTL-logic-compatible enable pin that reduces power consumption to nearly zero when disabled. It is stable with low-ESR ceramic capacitors, making it suitable for space-constrained power applications.

Key features include current limit, thermal shutdown, and faster transient response. The regulator is available in the Teeny™ SC-70-5 package, suitable for surface mount applications. Its operating temperature range is -40°C to +125°C.

Applications include cellular phones, pagers, battery-powered equipment, laptops, notebooks, palmtop computers, and general consumer/personal electronics where a stable, low-noise power supply is critical.
