| RT9165 150mA 3-Terminal Positive Regulator General Description The RT9165 is a positive low dropout regulator designed for applications requiring low dropout performance at full rated current. The device is available in fixed output voltage of 5.0V or 8.0V. The RT9165 provides excellent regulation over line, load, and temperature variations. The other features include low dropout performance at a maximum of 1.3V at 150mA, fast transient response, internal current limiting, and thermal shutdown protection of the output devices. The RT9165 is a three-terminal regulator compatible with industrial LM78L05/L08 and available in surface mount SOT-89 package. 123 Features Low Dropout, Maximum 1.3V at 150mA Fast Transient Response 3% Total Output Regulation 0.5% Line Regulation 0.5% Load Regulation SOT-89 and TO-92 Packages Pin Configurations Part Number RT9165-CZ (Plastic TO-92) Pin Configurations 1.
