The RT9167A-18GB Low Dropout Regulators (LDO) from Richtek is a 3.3V, 600mA, low dropout regulator, packaged in a SOT-23-5 RoHS compliant package. It offers over current protection and thermal shutdown in a very small form factor. It also provides current limiting, enabling the user to safely optimize input resistor settings. With its low dropout voltage, it provides better power efficiency and significantly reduces the power consumption of current-limited applications. The RT9167A-18GB provides superior performance in terms of line and load regulation, ripple rejection and power supply noise. Additionally, it is designed to ensure low output voltage noise, making it ideal for noise sensitive applications. The device is available in an RoHS compliant package and is capable of operating over a wide temperature range of -40°C to +125°C.
