Working Principle of LD1585CD2T18R

The LD1585CD2T18R works on the principle of linear voltage regulation, employing a voltage divider to generate a voltage reference signal that is compared to an input voltage. When the input voltage exceeds the reference signal, the output is reduced and vice versa. The device achieves a maximum output ripple of 8mV; this helps reduce power dissipation due to noise generated by the voltage regulator. Moreover, the device also has an adjustable current limiting feature which helps to protect it against short circuit and heavy current draw. The device is fully protected against current and junction temperature limits.

The device is can be easily set-up and configured to provide a stable supply voltage, according to the user\'s requirements. The device can offer up to 11S or a 2S standby time so that it can be efficiently used in the application fields. It provides very high efficiency (up to 90%) with its integrated amplifier and MOSFET which increases the power conversion efficiency and reduces the heat dissipation. The device also comes integrated with a feedback protection diode for reverse current over-load protection.
