MIC5245 Micrel MIC5245 150mA µCap CMOS LDO Regulator Final Information General Description Features The MIC5245 is an efficient, precise CMOS voltage regulator • Ultralow dropout—100mV @ 100mA optimized for ultra-low-noise applications. The MIC5245 of- • Ultralow noise—30µV(rms) fers better than 1% initial accuracy, extremely low dropout • Stability with tantalum or ceramic capacitors voltage (typically 150mV at 150mA) and constant ground • Load independent, ultralow ground current current over load (typically 100µA). The MIC5245 provides a • 150mA output current very low noise output, ideal for RF applications where quiet • Current limiting voltage sources are required. A noise bypass pin is also • Thermal Shutdown available for further reduction of output noise. • Tight load
