Analog Devices Inc. ADR3630 High Current Output Voltage References
Analog Devices Inc. ADR3630 High Current Output Voltage References are low power, high precision power management IC voltage references featuring a 3ppm/°C (maximum) temperature coefficient for the B grade in an 8-lead MSOP package. Capable of sourcing up to 70mA, the ADR3630 is an exceptional replacement to standard low dropout (LDO) regulators. A low thermal hysteresis (7ppm) and low long-term drift (160ppm at 3500Hr) improve system lifetime accuracy. Specified over the -40°C to +125°C operating temperature range, a minimum load capacitance of 0.1μF is required for operation. For high accuracy, the output voltage and temperature coefficient are trimmed during production using the ADI, proprietary DigiTrim® technology.
