Description
The NJW4109 is a 45 V, IO = 500 mA low dropout regulator with power-good. Power-good outputs whether the output voltage is within the normal range as a flag and notifies the MCU of the abnormal state. This device achieves fast transient response and offers stable output voltage even at line or load fluctuations. The NJW4109 provides outstanding high output voltage accuracy that guaranteed ±1.0% under the conditions of VIN = VO + 1 V to 40 V, IO = 0mA to 500 mA. Moreover, wide operating voltage, wide operating temperature, and power-good output make the NJW4109 ideal for automotive equipment or applications that require high reliability.
