Architecture and Working Principle

FP1LDLD035MR2XO’s architecture is specifically designed to meet the needs of ultra-low power applications. It is designed as a dual-input, dual-output, low drop-out regulator (LDO). This LDO utilizes a wide input voltage range, from 26V to 5V and provides an adjustable output voltage range from 0.8V to 4.5V. Furthermore, the device enters a low quiescent state when VIN is applied and shows fast transient response behaviour when the load current is changed.The device employs a push-pull inductor-less architecture with low-noise, low-dropout and low-emission operation, along with high-efficiency characteristics. The use of innovative chip design enables the device to reduce switch noise and harmonic distortion during load transients, thus providing good dynamic performance. Moreover, the device is protected against input reverse polarity as well as over temperature and over current conditions.The Special Transient Voltage Protection (TVP) feature uses an avalanche-resistant P-N junction diode that automatically limits turn-on surge currents and protects the device in the event of an input surge that exceeds the reverse breakdown voltage (Vb). The TVP feature is especially beneficial for protecting the device from inrush currents. It also enhances the thermal performance of the device, allowing higher pulse current ratings.The device is equipped with a control logic circuit that monitors the voltage at both the inputs and automatically adjusts the operating parameters to maintain the desired output voltage. The control circuit is also monitored to detect the connection or disconnection of the second input source and adjusts its internal operating parameters accordingly.In summary, FP1LDLD035MR2XO is an advanced integrated circuit, designed to reduce power consumption and offer superior performance in a variety of applications. It is highly efficient and robust, providing excellent protection against both voltage and thermal events. It is also flexible and user-friendly, allowing for adjustable output voltages to meet the demands of different applications. Furthermore, its specialized Transient Voltage Protection (TVP) feature offers superior protection against inrush current and enhances thermal performance.
