AP7345D Pin Descriptions Pin Number Pin Name Function
GND 1, 4 Ground VOUT1 2 Channel 1 Output Voltage pin VOUT2 3 Channel 2 Output Voltage pin
T
Chanel 2 Enable pin. This pin should be driven either high or low and must not
C
EN2 5 be floating. Driving this pin high enables channel 2 output, while pulling it low
U
puts Chanel 2 regulator into shutdown mode.
D
V
O
IN2 6 Channel 2 Input Voltage pin
R
VIN1 7 Channel 1 Input Voltage pin
P
Chanel 1 Enable pin. This pin should be driven either high or low and must not
W
EN1 8 be floating. Driving this pin high enables channel 1 output, while pulling it low
E
puts Chanel 1 regulator into shutdown mode.
N
In PCB layout, prefer to use large copper area to cover this pad for better — Thermal PAD thermal dissipation, then connect this area to GND or leave it open. However do not use it as GND electrode function alone.
