Additional Details

The TCR5SB25(TE85L,F) operates from an input voltage range of approximately 2.7V to 5.5V. It delivers a fixed output voltage of 2.5V with high accuracy. The 'TE85L,F' 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.
