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.
