Pin Descriptions
Pin Name Description
GND1/2 Ground
3.3V (Vout1)
The output of the regulator. A minimum of 10uF capacitor (0.15 Ω ≤ ESR ≤ 20Ω) must be
connected from this pin to ground to insure stability. 2.5V/1.8V
(Vout2)
VIN1/2
The input pin of regulator. Typically a large storage capacitor (0.15 Ω ≤ ESR ≤ 20Ω) is
connected from this pin to ground.
