Table 4-2 Pin FMA for Device Pins Short-Circuited to Ground
Pin NamePin No.Description of Potential Failure Effect(s)Failure Effect Class
OUT1Output 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
NC2Normal operation.D
GND3Normal operation.D
EN4LDO will not start up due to EN being grounded.B
NC5Normal operation.D
IN6Output voltage will be near/at ground.B
Table 4-3 Pin FMA for Device Pins Open-Circuited
Pin NamePin No.Description of Potential Failure Effect(s)Failure Effect Class
OUT1No impact to the LDO, but components downstream will not be powered.D
NC2Normal operation.D
GND3GND is floating. Output voltage will be incorrect as it is no longer referenced to GND.B
EN4EN pin voltage will float as the LDO contains no internal pullup/pulldown. LDO is in unknown state.B
NC5Normal operation.D
IN6No input to LDO. Input and output will float to an unknown voltage.B
Table 4-4 Pin FMA for Device Pins Short-Circuited to Adjacent Pin
Pin NamePin No.Shorted toDescription of Potential Failure Effect(s)Failure Effect Class
OUT12 - NCNormal operation.D
NC23 - GNDNormal operation.D
GND34 - ENLDO will not start up due to EN being grounded.B
EN45 - NCNormal operation.D
NC56 - INNormal operation.D
IN61 - OUTNo output voltage regulation. Output voltage is the same as input voltage.B
Table 4-5 Pin FMA for Device Pins Short-Circuited to VIN
Pin Name Pin No. Description of Potential Failure Effect(s) Failure Effect Class
OUT 1 No output voltage regulation. Output voltage is the same as input voltage. B
NC 2 Normal operation. D
GND 3 Output voltage will be near/at ground. B
EN 4 LDO will startup/shutdown when VIN is above EN threshold. D if VIN = VEN by design, B otherwise
NC 5 Normal operation. D
IN 6 Normal operation. D
