Rochester Electronics PMIC - Voltage Regulators - Linear NCV4949PDG

The NCV4949PDG is a low dropout linear voltage regulator designed to provide a stable 5.0 V output with a maximum output current of 100 mA. It operates within a DC supply voltage range of 5.0 V to 28 V and can withstand transient supply voltages up to 40 V. The device features a very low dropout voltage of less than 0.4 V, making it suitable for applications where power efficiency is critical. This regulator includes additional functionalities such as a reset circuit that monitors the output voltage and a voltage sense comparator. It also offers programmable reset pulse delay and incorporates thermal shutdown and short circuit protections to enhance reliability. The NCV4949PDG is particularly suited for automotive applications, as indicated by its NCV prefix, which signifies compliance with automotive standards. The device is available in a Pb-free SOIC-8 EP package, ensuring compatibility with environmentally friendly manufacturing processes.
