of 8

FEATURES

Input voltage range: 2.2 V to 5.5 V

Output current range: 0 mA to 150 mA

Output voltage accuracy: ±1%

Operating temperature range: −40°C to +125°C

GENERAL DESCRIPTION

The ADP150 evaluation board is used to demonstrate

the functionality of the ADP150 linear regulator.

Simple device measurements such as line and load regulation,

dropout voltage, and ground current can be demonstrated with

only a single voltage supply, a voltage meter, a current meter,

and load resistors.

For more information about the ADP150 linear regulator, see

the ADP150 data sheet.

Evaluation Board User Guide UG-054 EVALUATION BOARD HARDWARE EVALUATION BOARD CONFIGURATIONS Table 1. Evaluation Board Hardware Components The ADP150 evaluation board is supplied with different components, depending on the version that is ordered. Components common to both versions are C2, C4, and J1. Figure 3 and Figure 4 show the schematics of these evaluation board configurations. Table 1 describes the components.

Output Voltage Measurement Setup, TSOT VOLTAGE SOURCE VOLTMETER 08518-006 LOAD Figure 6. Output Voltage Measurement Setup, WLCSP Figure 5 and Figure 6 show how the evaluation board can be connected to a voltage source and a voltage meter for basic output voltage accuracy measurements. A resistor can be used as the load for the regulator.

Evaluation Board User Guide UG-054 LINE REGULATION MEASUREMENTS DROPOUT VOLTAGE MEASUREMENTS For line regulation measurements, the output of the regulator is monitored while its input is varied. For good line regulation, the output must change as little as possible with varying input levels. To ensure that the device is not in dropout mode during this measurement, VIN must be varied between VOUTNOM + 0.4 V (or 2.2 V, whichever is greater) and VINMAX.

Ground Current Measurement Setup, WLCSP Figure 10 and Figure 11 show how the evaluation board can be connected to a voltage source and an ammeter for ground current measurements. A resistor can be used as the load for the regulator.

Evaluation Board User Guide UG-054 250 When these steps are completed, the voltage source can be turned on. If J1 is inserted (connecting EN to VIN for automatic startup), the regulator powers up. IOUT = 150mA GROUND CURRENT (µA) 200 GROUND CURRENT CONSUMPTION Ground current measurements can determine how much current the internal circuits of the regulator consume while the circuits perform the regulation function. To be efficient, the regulator must consume as little current as possible.
