MIC5259 Part Attribute
- Description The MIC5259 is an efficient CMOS voltage regulator optimized for low-noise applications. It offers 1.5% initial accuracy, low dropout voltage (300mV at 300mA), and low ground current (typically 105µA at light load). The MIC5259 provides a very low noise output, ideal for RF applications where a clean voltage source is required. The MIC5259 has a high PSRR even at low supply voltages, critical for battery-operated electronics. A noise bypass pin is also available for further reduction of output noise. Designed specifically for handheld and battery-powered devices, the MIC5259 provides a TTL logic-compatible enable pin. When disabled, power consumption drops to nearly zero. The MIC5259 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications; a critical issue in handheld wireless devices. Key features include current limit, thermal shutdown, faster transient response, and an active clamp to speed up device turnoff. The MIC5259 is available in Thin SOT-23-5 package in a wide range of output voltages.
