Description
The NJW4250 is voltage tracker with 45V input voltage (absolute maximum rating) and 50mA output current. The adjustable adjust input voltage from 2.5V to 36V, and ±5mV output voltage accuracy over the operating temperature range are guaranteed. NJW4250 has high-precision tracking output voltage, thermal shutdown function and overcurrent protection function, is ideal for off-board sensors in automotive applications that require high reliability. Low quiescent current of 40μA and SOT-23-5 small package make the NJW4250 achieves low power and space saving of the system.
