The maximum input voltage that can be applied to the TPS71533DCKR is 5.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 1uF and a maximum equivalent series resistance (ESR) of 1 ohm, as specified in the datasheet.
The maximum output current that the TPS71533DCKR can deliver is 150mA, as specified in the datasheet. Exceeding this current may cause the device to overheat or malfunction.
The output voltage of the TPS71533DCKR can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors connected to the FB pin, Vin is the input voltage, and Vref is the internal reference voltage (1.2V).
The EN (enable) pin on the TPS71533DCKR is used to enable or disable the device. When the EN pin is pulled high, the device is enabled and the output voltage is regulated. When the EN pin is pulled low, the device is disabled and the output voltage is turned off.
