1 GND Ground 2 VOUT3 Channel 3 Output Voltage pin 3 VOUT4 Channel 4 Output Voltage pin Enable Pin to control CH2&CH4 4 EN2 This pin should be driven either high or low. Driving this pin high enables the regulator, while pulling it low puts the regulator into shutdown mode 5 VOUT2 Channel 2 Output Voltage pin 6 VDD Power Input Pin 7 VOUT1 Channel 1 Output Voltage pin Enable Pin to control CH1&CH3 8 EN1 This pin should be driven either high or low. Driving this pin high enables the regulator, while pulling it low puts the regulator into shutdown mode — This pad must be connected for thermal dissipation. Electrically it may be left open or connected to Thermal Pad Ground. This does not replace the connection that is required for pin 1. AP7348 2 of 15 October 2019 Document number: DS42124 Rev. 2 - 2
