- 8-Lead MSOP package
The ADR3625\ADR3630\ADR3650 are low power, high precision voltage references that feature a maximum temperature coefficient of 3 ppm/°C for the B grade in an 8-lead MSOP. Capable of sourcing up to 70 mA, the ADR3625\ADR3630\ADR3650 are an exceptional replacement to standard low dropout (LDO) regulators. For high accuracy, the output voltage and temperature coefficient are trimmed during production using the Analog Devices, Inc., proprietary DigiTrim® technology.
The low thermal hysteresis (7 ppm) and low long-term drift (160 ppm at 3500 Hr) improve system lifetime accuracy. A minimum load capacitance of 0.1 μF is required for operation. The ADR3625\ADR3630\ADR3650 is specified over the –40°C to +125°C operating temperature range.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-ADR3625EBZ evaluation board is for evaluating the ADR3625 that is included on the board.
Figure 1 in the user guide shows the EVAL-ADR3625EBZ evaluation board. VIN, GNDF, and VOUTF are installed with the binding post for simple connection with the most common bench setup connector. Printed circuit board (PCB) traces are also provided for the GNDS and VOUTS pins, the passives, and the Subminiature Version B (SMB) for more sophisticated setup and usage.
Full specifications of the device under test (DUT) are available in the ADR365 data sheet, which should be consulted in conjunction with the user guide when using the EVAL-ADR3625EBZ evaluation board.
