The MIC5259-2.8YD5-TR is an efficient CMOS linear voltage regulator optimized for low-noise applications, offering a fixed 2.8V output at up to 300mA. It provides 1.5% initial accuracy and a low dropout voltage of 300mV at 300mA.
This regulator is ideal for RF applications requiring a clean voltage source due to its very-low-noise output and high Power Supply Rejection Ratio (PSRR) of 70dB at 1kHz. It is designed for handheld and battery-powered devices, featuring a TTL-logic-compatible enable pin that reduces power consumption to nearly zero when disabled. The device is stable with low-ESR ceramic capacitors, reducing board space.
Key features include current limit, thermal shutdown, and an active clamp for faster turn-off. The MIC5259-2.8YD5-TR is supplied in a 5-pin TSOT-23-5 package, suitable for surface mounting.
Applications include cellular phones, pagers, battery-powered equipment, laptop computers, and consumer electronics where a stable, low-noise power source is critical.
