The Microchip MIC5317 is a high-performance 150mA low dropout (LDO) regulator offering high power supply rejection (PSRR) in an ultra-small package. It operates from an input voltage of 2.5V to 6.0V and provides output voltages from 1.0V to 3.6V, making it ideal for USB port and AC adapter applications. The MIC5317 features low quiescent current, low dropout voltage, and thermal-shutdown and current-limit protection, ensuring reliable performance in a variety of industrial and consumer applications. Available in UDFN, SOT23-5, and TSOT23-5 packages, it's perfect for space-constrained designs.
