MIC5247 Micrel MIC5247 150mA Low-Voltage �Cap Linear Regulator General Description Features The MIC5247 is an efficient, precise low voltage CMOS � Ultra-low-noise voltage regulator optimized for ultra-low-noise applications. � Low voltage outputs The MIC5247 offers better than 1% initial accuracy, and 85�A � Load independent, ultra-low ground current: 85�A constant ground current over load (typically 85�A). The � 150mA output current MIC5247 provides a very low noise output, ideal for RF � Current limiting applications where quiet voltage sources are required. A � Thermal Shutdown noise bypass pin is also available for further reduction of � Tight load and line regulation output noise. � �Zero� off-mode current � Stability with low-ESR capacitors Designed specifically for han
