The ChipLink CL9193A18L5M is a SOT-23-5 Low Drop Out (LDO) Linear Voltage Regulator that is RoHS compliant. It operates off of a 5V input voltage, and produces a regulated 0.9V output voltage with current up to 500mA. It features an ultra-low dropout voltage, high output accuracy, and an ultra-low quiescent current. This part also contains built-in over-current and short-circuit protection to ensure stable operation and maximum protection for the device. The CL9193A18L5M is ideal for applications in handheld and battery-powered applications, with its small size, low power consumption, and high efficiency.
