Microchip Technology, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MIC5259-1.8YD5-TR

The MIC5259-1.8YD5-TR is a low-noise CMOS linear voltage regulator designed for efficient performance in battery-powered and handheld devices. It provides a regulated output voltage of 1.8V with a maximum output current of 300mA. The device features a low dropout voltage of 300mV at full load, ensuring efficient operation even with minimal input-output voltage differential. With an initial output accuracy of 1.5% and a power supply rejection ratio (PSRR) of 70dB at 1kHz, it is suitable for applications requiring stable voltage with minimal noise, such as RF devices. The MIC5259-1.8YD5-TR operates within an input voltage range of 2.7V to 6.0V and has a low quiescent current of 105µA, which drops to nearly zero when disabled via its TTL-compatible enable pin. The device is stable with low-ESR ceramic capacitors, making it ideal for compact designs. Additional features include thermal shutdown and current limit protection, enhancing reliability in various applications, including cellular phones, portable electronics, and consumer devices. The product is available in a compact 5-pin Thin SOT-23 package, facilitating space-efficient integration into electronic designs.
