Pin Name

Pin Function

1

VIN1

Voltage Input for LDO1.

2

VIN2

Voltage Input for LDO2.

3

VBIAS

Bias Input Voltage.

4

EN1

Enable Input for LDO1. Active High Input. Logic High = On; Logic Low = Off; Do

not leave floating.

5

EN2

Enable Input for LDO2. Active High Input. Logic High = On; Logic Low = Off; Do

not leave floating.

6

CSET2

Delay Set Input for POR2. Connect an external capacitor to GND to set the

delay for POR2. When left open, there is no delay. Do not ground this pin.

7

POR2

Power-on Reset for LDO2.

8

GND

Ground.

9

CBYP

Bypass: Connect a capacitor to ground to improve output noise and PSRR.

10

/VSC2

Voltage Select Input for LDO2. Active Low Input. Logic High = Full Output

Voltage; Logic Low = Low Output Voltage. Do not leave floating.

11

VOUT2

Output of regulator 2.

12

VOUT1

Output of regulator 1.
