The LN1121P332MR-G is a Low Dropout (LDO) regulator manufactured by NATLINEAR, and it has been designed in a SOT-23-3L (Surface-mounted Technology) package. It is RoHS compliant. It is ideal for applications that require low noise, high efficiency, and ultra-low quiescent current. The LN1121P332MR-G features an output voltage of 3.3V, an ultra-low dropout voltage of 700mV, and a wide input voltage range of 2V to 5.5V. It also offers excellent transient response while maintaining low dropout and fast settling time. The device has short-circuit protection, thermal shutdown, and over- and under-voltage lockout. The LN1121P332MR-G is ideal for portable applications, such as PDAs, portable networking equipment, and cellular phones.
