EVALUATION BOARD HARDWARE

EVALUATION BOARD CONFIGURATIONS

The ADP7183 evaluation board comes supplied with different

components, depending on which version (fixed or adjustable) of

the ADP7183 evaluation board is ordered. Components common

to both versions are C1, C2, C3, C4, C5, and JP1. The R1 and R2

resistors set the output voltage of the adjustable evaluation board.

Figure 9 and Figure 10 show the schematics of these evaluation

board configurations, and Table 1 describes the hardware

components.

The ADP7183 fixed option uses a −3.3 V output model. Do not

connect R1 and R2 for the fixed output option.

The adjustable output of the ADP7183 has a range of −0.5 V to

−4.5 V. The output voltage is set by

With the values shown in Figure 10, the output voltage is

approximately −2.5 V.

Description

U1

ADP7183 linear regulator.

For the fixed output option, U1 uses the −3.3 V output option of the ADP7183.

For the adjustable output option, U1 uses the adjustable option of the ADP7183 and is set to −2.5 V.

C1

C2

C3

C4

C5

JP1

Jumper (connects EN to VIN for automatic startup).

R1, R2

Part of the external resistor divider (composed of R1 and R2 that sets the output voltage for the adjustable option).
