-
Description
The NP4271 is a using Bi-CMOS process, Io = 500 mA low dropout regulator with watchdog timer and reset functions. The output voltage is detected by window detection that can detect the high-side voltage and low-side voltage. The NP4271 offers outstanding high output voltage accuracy that guaranteed ±2% under the conditions of VIN = VO+ 1V to 40 V, IO = 5 mA to 500 mA, and Ta = −40°C to 125°C. This feature makes the device well suited as automotive ECUs and industrial applications.
