The BCT2193EJR18-TR is an ultra-low quiescent current linear voltage regulator (LDO) with SOT-89-3 package and ROHS (Restriction of Hazardous Substances) compliance, manufactured by BROADCHIP, that has a fixed output voltage of 1.8V and a maximum output current of 100mA. It is well suited for low power applications and features an accurate output voltage regulation of less than 1.8%, thermal limitation, short circuit protection, under voltage lockout, low quiescent current of less than 90uA and high output voltage ripple rejection of 40db. This device is available in a small SOT-89-3 package that allows for high flexibility of PCB layout and offers ease-of-use with its stable performance and low quiescent current. It is ideal for applications that require a low noise, low quiescent power solution.
