500 μA to

800 m A Output voltage accuracy: ±2% Operating temperature range: ?40°C to +125°C GENERAL DESCRIPTION The ADP1752/ADP1753 evaluation board is used to demon- strate the functionality of the ADP1752/ADP1753 series of linear regulators. Simple device measurements, such as line and load regulation, dropout, and ground current, can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
