The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160 low-dropout, micropower, three-terminal voltage references offer 2.5V, 4.096V, 4.5V, 5.0V, and adjustable (1.23V to 12.4V) output voltages, respectively.
The MAX61xx family provides low‑dropout, micropower, three‑terminal voltage references with fixed outputs of 2.5 V, 4.096 V, 4.5 V, 5.0 V and an adjustable range of 1.23 V to 12.4 V. With a typical 200 mV dropout and a supply current of about 75 µA that is independent of input voltage, these devices are suited for 3 V and 5 V battery‑powered systems.
Key specifications include a typical temperature coefficient of 15 ppm/°C (max 50 ppm/°C), stability with capacitive loads up to 10 nF, and availability in 3‑pin SOT‑23, 4‑pin SOT‑143 (MAX6160 only), and 8‑pin SO packages. The datasheet also provides absolute maximum ratings, electrical characteristics, typical operating curves, and recommended application circuits.
