Working Principle

The BA90BC0T uses a linear voltage regulation circuit to convert an unregulated DC input voltage to a regulated and stable output voltage. The input voltage is adjusted by a resistor and capacitor network, which form an RC low-pass filter. When the input voltage changes, the resistor-capacitor network compensates for the change and maintains the output voltage constant. The output voltage can be adjusted by the resistor and capacitor networks. Additionally, the device has an over-temperature protection feature which can shut down the device when the junction temperature exceeds a specified limit.

The BA90BC0T also has an output current regulation and overcurrent protection feature. This feature prevents damage to the device and other components due to overcurrent conditions. The output current can be adjusted by a resistor, which can be located on the device or external to it. Additionally, the device has an input reverse polarity protection feature which prevents damage due to accidental reverse power supply.
