The 800mA LT3088 and LT3089 can be thought of as lower current LT3081 regulators all with a wider safe operating area, plus additional protection and monitoring features. The LT3088 and LT3089 both have improved PSRR over the LT3081’s performance. The LT3088 is a “modernized” version of the popular LT1117, and is pin- compatible with both the LT1117’s SOT-223 and DD-Pak packages. Use the LT3081 if higher output current and the monitoring features are required.
