Figure 4-1 shows the TLV733P-Q1 pin diagram for the WSON-6 package. For a detailed description of
the device pins please refer to the Pin Configuration and Functions section
in the TLV733P-Q1 data sheet.
Table 4-2 Pin FMA for Device Pins
Short-Circuited to GroundPin Name | Pin No. | Description of Potential Failure Effect(s) | Failure Effect Class |
---|
OUT | 1 | Output voltage will be near/at ground. Device is in current limit.
It may cycle in and out of thermal shutdown depending on power
dissipation. | B |
NC | 2 | Normal operation. | D |
GND | 3 | Normal operation. | D |
EN | 4 | LDO will not start up due to EN being grounded. | B |
NC | 5 | Normal operation. | D |
IN | 6 | Output voltage will be near/at ground. | B |

Open-CircuitedPin Name | Pin
No. | Description of Potential Failure Effect(s) | Failure
Effect Class |
---|
OUT | 1 | No impact to the LDO, but components downstream will not be
powered. | D |
NC | 2 | Normal operation. | D |
GND | 3 | GND is floating. Output voltage will be incorrect as it is no longer
referenced to GND. | B |
EN | 4 | EN pin voltage will float as the LDO contains no internal
pullup/pulldown. LDO is in unknown state. | B |
NC | 5 | Normal operation. | D |
IN | 6 | No input to LDO. Input and output will float to an unknown
voltage. | B |
