CAT6221-PPTD-GT3 ON Semiconductor, CAT6221-PPTD-GT3 Datasheet - Page 2

• Manufacturer Part Number: CAT6221-PPTD-GT3
• Description: LDO DUAL 300MA
• Manufacturer: ON Semiconductor

Pin Function
VIN is the supply pin for the LDO. A small 1 mF ceramic
bypass capacitor is required between the V
near the device. When using longer connections to the power
supply, C
operating input voltage range is from 2.3 V to 5.5 V.
EN1 & 2 are the enable control logic (active high) for the
regulator outputs.
VOUT1 & 2 are the LDO regulator outputs. A small 1 mF
ceramic bypass capacitor is required between the VOUT
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
NOTE:
1. The maximum allowable power dissipation at any T
2. The device is not guaranteed to work outside its operating rating.

GND is the ground reference for the LDO. The pin must be
connected to the ground plane on the PCB.
