Power Supply Circuitry
Three power supplies are required: ! Transformer with 5.5V min to 9V max ! External VIN with 3V min to 3.6 max ! External VBAT with 2.5V min to 3.6V max The power supply voltage is regulated with on-board circuitry. Input voltage on this connector should be included between 5.5V and 9V. This power supply input is NOT protected against polarization inversion.

Electrical Parameter Measurement
The AT73C239-EK1 is designed to allow easy measurement of electrical parameters on the board. Connectors are provided to perform voltage and current measurements. Measurements such as load regulation, line regulation, noise and PSRR can be performed on these pads.
4.2.1
AT73C239 Voltage Measurements Pads There are four "sense" pads that perfom voltage measurements on each LDO output delivered by the AT73C239. These four pads are described as follows: ! VO1 - Output Voltage of LDO1 (2.75V / 1.8V) ! VO2 - Output Voltage of LDO2 (1.8V / 1.5V) ! VO3 - Output Voltage of LDO3 (1.8V / 1.5V / 1.23V) ! VO4 - Output Voltage of LDO4 (1.8V / 1.5V / 1.2V) Figure 4-2 . Pads For Voltage Measurement
