The MIC5247-1.8BD5-TR is an efficient and precise, low-voltage CMOS voltage regulator optimized for ultra-low noise applications. The MIC5247-1.8BD5-TR offers better than 1% initial accuracy and 85mA constant ground current over load (typically 85mA). The MIC5247-1.8BD5-TR provides a very low-noise output, ideal for RF applications where quiet voltage sources are required. A noise bypass pin is also available for further reduction of output noise.
Designed specifically for handheld and battery-powered devices, the MIC5247-1.8BD5-TR provides a logic-compatible enable pin. When disabled, power consumption drops nearly to zero.
The MIC5247-1.8BD5-TR also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices.
Key features include current limit, thermal shutdown, a push-pull output for faster transient response, and an active clamp to speed up device turnoff. Available in IttyBitty® SOT-23-5 package, the MIC5247-1.8BD5-TR also offers a range of fixed output voltages.
