Description

General part information

MIC5259 Series

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.
