LDO voltage regulators provide ‘green’ solution for automotive applications
1 min read
ON Semiconductor has announced the launch of five new low and ultra low dropout (LDO) linear voltage regulators. The devices address a range of automotive applications such as rear camera modules, instrument clusters and body and chassis applications. They are optimised to deliver 150mA of output current.
The NCV8768 and NCV8769 regulators feature typical quiescent currents of 31 and 25µA, respectively. They are suitable for applications permanently connected to the battery. The NCV8768 features an enable function designed to further decreases the quiescent current to 1µA, as well as reverse output current protection. Both devices include current limit and thermal shutdown features.
The NCV8668 features a quiescent current of 38µA and an integrated window watchdog that allows the detection of microprocessor malfunctions. It has a quiescent current of 38µA, is optimised to deliver stable performance and requires a minimal number of external components. Other features include reset, a programmable delay time and an enable function.
The NCV8667 and NCV8669 both have a typical quiescent current of 28µA and are offered as replacements for ON's NCV4269 in applications where very low quiescent current is a requirement. With built in reset, delay and early warning functions, they are targeted at a range of voltage monitoring tasks.
