5A LOW DROPOUT POSITIVE ADJUSTABLE OR

FIXED-MODE REGULATOR

Vout

Vin

I/O TO263/

Function

Adjustable (Ground only for fixed mode)

I

1

A resistor divider from this pin to the Vout pin and ground sets the

output voltage (Ground only for Fixed-Mode).

The output of the regulator. A minimum of 10uF (0.15Ω ≤ ESR ≤

O

2

20Ω) capacitor must be connected from this pin to ground to

insure stability.

The input pin of regulator. Typically a large storage capacitor

(0.15Ω ≤ ESR ≤ 20Ω) is connected from this pin to ground to insure

I

3

that the input voltage does not sag below the minimum dropout

voltage during the load transient response. This pin must always be

1.4V (1.3V) higher than Vout in order for the device to regulate

properly.
