MIC5250 Micrel MIC5250 Dual 150mA µCap CMOS LDO Regulator Final Information General Description Features The MIC5250 is an efficient, precise dual CMOS voltage • Ultralow dropout—100mV @ 100mA regulator optimized for ultra-low-noise applications. The • Ultralow noise—30µV(rms) MIC5250 offers better than 1% initial accuracy, extremely low • Stability with ceramic, tantalum, or aluminum electrolytic dropout voltage (typically 150mV at 150mA) and constant capacitors ground current over load (typically 100µA). The MIC5250 • Load independent, ultralow ground current provides a very-low-noise output, ideal for RF applications • 150mA output current where quiet voltage sources are required. A noise bypass pin • Current limiting is also available for further reduction of output noise.
