2.1.2 Test Points

Table 2-2 contains the list of test point and descriptions of their function(s).

Table 2-2 Test Points
Schematic Reference Description
TP1 VOUT Test point. This test point is prior to 0 Ω R1, and directly connected to OUT pins of LDO.
TP2, TP3 VCOUT Test points. These test points are after the 0 Ω R1. They are on the COUT plane. TP2 is used for Bode signal injection along with TP8.
TP4 VOUT Test point. This test point is after L1 (populated with 0 Ω) in the output path. This testpoint is outside the feedback loop.
TP5 VIN Test point.
TP6 PG power good test point.
TP7 EN enable test point.
TP8 Feedback OUTS test point. Used for Bode signal injection along with TP2.
TP9 SS_SET test point. This node defines VOUT regulation, and soft start.
TP10 Bias test point, located on device side of the bias filter defined by R6 and C14.
TP11 GND test point.
TP12 Bias test point, located on source side of the bias filter defined by R6 and C14.
TP13 FB_PG test point.
TP14, TP15 GND test points.
