Working Principle

LP5996SDX-2828/NOPB linear voltage regulator works on the principle of controlling the output voltage by varyin gthe amount of voltage applied to a pass transistor that steers the current from the input voltage to the output. The pass transistor can be controlled in two ways: either with a resistor divider or with a feedback loop. In the case of the LP5996SDX-2828/NOPB family, it has a resistive voltage divider to control the pass transistor.The LP5996SDX-2828/NOPB family offers adjustable and fixed output voltage. The adjustable output voltage can be set by two external resistors connected to the FB pin. The fixed output voltage is set by the selection of the specific device type. The LV/HV switch pin is used to select either low or high voltage output.The LP5996SDX-2828/NOPB offers a thermal protection (OTP) feature that ensures the device is shutdown when the junction temperature exceeds a safe level, providing increased safety.
