TechnologiesThe LR1801G-33-SH2-R is an LDO (Low Dropout Regulator) designed and manufactured by Unisonic Technologies. It is an HSOP-8 package featuring RoHS compliance. The LR1801G-33-SH2-R is intended for use in applications requiring low power consumption, high load current, high accuracy, transient responses, and high efficiency, with an output voltage of 3.3V and a nominal dropout voltage of 0.3V at a rated current of 1A. The IC features a high PSRR (Power Supply Rejection Ratio) of 66dB, low temperature coefficients, low noise, and fast start-up transient response. The low quiescent current consumption and low ESR (Equivalent Series Resistance) make it an effective power saving solution. The LR1801G-33-SH2-R also features a Low-Current Shutdown mode which reduces the current consumption to a level of 1uA. In addition, the device has protection against undervoltage and overvoltage conditions, high input voltage transients, and reverse current protection.
