Additional Details

The TCR5SB28A T5L,F,T operates from an input voltage range of approximately 2.9V to 5.5V. It delivers a fixed output voltage of 2.8V with high accuracy. The 'T5L,F,T' designation refers to the specific packaging and taping used for this variant, which is optimized for automated surface-mount assembly processes.  The operating temperature range is generally -40°C to +85°C.  The maximum output current is typically in the 300mA to 500mA range, depending on the operating conditions.  Input and output capacitors are required for stability; consult the datasheet for recommended values and ESR characteristics. The overcurrent protection threshold is usually set to a value above the maximum rated output current, providing a safety margin. The thermal shutdown temperature is typically around 150°C.
