The maximum input voltage that can be applied to the LTC3300 is 5.5V, although the recommended operating range is 3.15V to 5.5V.
To ensure the LTC3300 is in a stable operating condition during startup, make sure the input voltage rises monotonically and the EN pin is pulled high after the input voltage has reached 2.5V.
The TRACK pin is used to track the output voltage of the regulator. It can be connected to an external resistor divider network to set the output voltage. The TRACK pin should be connected to a voltage source that is within 1.2V to 5.5V of the input voltage.
The output voltage of the LTC3300 can be calculated using the formula: VOUT = VTRACK x (1 + R1/R2), where R1 and R2 are the resistors connected to the TRACK pin and VTRACK is the voltage at the TRACK pin.
The maximum output current that the LTC3300 can deliver is 500mA, although the recommended operating current is up to 300mA for optimal performance and reliability.
