Additional Details
The TCR5SB47(TE85L,F) typically operates with an input voltage slightly higher than 4.7V (e.g., 4.8V to 5.5V). It delivers a fixed output voltage of 4.7V with a specified tolerance. The 'TE85L,F' designation refers to the specific packaging and taping configuration, optimized for automated surface-mount assembly. The operating temperature range is generally -40°C to +85°C. The output current capability is typically in the 300mA to 500mA range, depending on the operating conditions. External input and output capacitors are required for stability, and their recommended values and ESR characteristics should be consulted in the datasheet. Overcurrent protection is usually set to trigger slightly above the maximum rated output current. Thermal shutdown typically occurs at a temperature around 150°C.
