The LP3980S-33B5F Linear Voltage Regulator (LDO)ROHS is a low-power, 2.6V to 5.5V voltage regulator with an output current of up to 200mA. This part has a SOT-23-5 package and offers low dropout voltage (< 300mV) and fast transient response. It is a very low noise regulator with a quiescent current of just 2µA typical. It also offers enhanced protection features such as Three-State Shutdown, Adjustable Current Limit and Over-temperature Protection. This regulator is suitable for various applications such as cellular phones, PDAs, digital cameras, MP3 players, etc.
