ELECTRONICSThe SD5088A28E is a Low Dropout Regulator (LDO) SOT89-3 RoHS manufactured by SHOUDING ELECTRONICS. It is a fixed output voltage regulator, providing a stable output voltage of 2.8V with a maximum output current of 500mA. It is designed to operate with a wide input voltage range from 2.7 to 6.0 Vdc, and its ripple rejection reaches 65 dB. The device features ultra-low dropout voltage (170mV typical at full load), low quiescent current (50uA typical at full load) and excellent thermal characteristics. It also includes various protection features, such as over voltage protection and current limiting protection. The device is packaged in a compact SOT89-3 RoHS package, thus providing ideal solutions for space-limited designs.
