The LM1117M-3.3/TR with Dropout Regulators (LDO) SOP-8 RoHS manufactured by HGSEMI is a low-dropout (LDO) linear regulator designed for low-noise applications. Its features include a 3.3 V fixed output voltage, ultra-low dropout voltage (260 mV typical), very low quiescent current (2.5 mA typical), low noise (35 µVrms, 10 Hz to 100 kHz), and low temperature coefficient (200 ppms/°C typical). Additionally, it has tight turn-on voltage accuracy (±1.0%), current limit, and thermal protection. The unit is housed in an industry standard 8-pin SOP package and is RoHS compliant. Its applications include low power, high-reliability, and extended battery-life applications.
