Setting Up the Evaluation Board for the ADP151
FEATURES
Input voltage range: 2.2 V to 5.5 V
Output current range: 0 mA to 200 mA
Output voltage accuracy: ±1%
Operating temperature range: −40°C to +125°C
GENERAL DESCRIPTION
The ADP151 evaluation board is used to demonstrate the
functionality of the ADP151 series of linear regulators.
Simple device measurements such as line and load regulation,
dropout voltage, and ground current can be demonstrated with
only a single voltage supply, a voltmeter, a current meter, and
load resistors.
For more information about the ADP151 linear regulator, see
the ADP151 data sheet.
