GENERAL DESCRIPTION

The ADR3625 is a low power, high precision voltage reference that

features 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 is 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 4500 Hr) improve system lifetime accuracy. A minimum

load capacitance of 0.1 μF is required for operation. The ADR3625

is specified over the –40°C to +125°C operating temperature range.
