JAJSO99 april 2023 TPS552892-Q1
PRODUCTION DATA
To minimize the power dissipation of the internal LDO when both input voltage and output voltage are high, an external 5-V power source can be applied at the VCC pin to supply the TPS552892-Q1. The external 5-V power supply must have at least 100-mA output current capability and must be within the 4.75-V to 5.5-V regulation range. When the EXTVCC pin is connected to logic low, the device selects the external power supply to supply the device through VCC pin. When the EXTVCC pin is connected to logic high or is left floating, the device selects internal LDO.
