Table 4-6 Pin FMA for Device Pins Short-Circuited to Ground
Pin NamePin No.Description of Potential Failure Effect(s)Failure Effect Class
IN1Output voltage will be near/at ground.B
GND2Normal operation.D
EN3LDO will not start up due to EN being grounded.B
NC4Normal operation.D
OUT5Output 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
Table 4-7 Pin FMA for Device Pins Open-Circuited
Pin NamePin No.Description of Potential Failure Effect(s)Failure Effect Class
IN1No input to LDO. Input and output will float to an unknown voltage.B
GND2GND is floating. Output voltage will be incorrect as it is no longer referenced to GND.B
EN3EN pin voltage will float as LDO contains no internal pullup/pulldown. LDO is in unknown state.B
NC4Normal operation.D
OUT5No impact to the LDO, but components downstream will not be powered.D
Table 4-8 Pin FMA for Device Pins Short-Circuited to Adjacent Pin
Pin NamePin No.Shorted toDescription of Potential Failure Effect(s)Failure Effect Class
IN12 - GNDOutput voltage will be near/at ground.B
GND23 - ENLDO will not start up due to EN being grounded.B
EN34 - NCNormal operation.D
NC45 - OUTNormal operation.D
OUT51 - INNo output voltage regulation. Output voltage is the same as input voltage.B
Table 4-9 Pin FMA for Device Pins Short-Circuited to VIN
Pin Name Pin No. Description of Potential Failure Effect(s) Failure Effect Class
IN 1 Normal operation. D
GND 2 Output voltage will be near/at ground. B
EN 3 LDO will startup/shutdown when VIN is above EN threshold. D if VIN = VEN by design, B otherwise
NC 4 Normal operation. D
OUT 5 No output voltage regulation. Output voltage is the same as input voltage. B
