PIN DESCRIPTIONS

Thedescriptionsof the pins arelistedinTable2-1.

TABLE 2-1:

PIN FUNCTION TABLE

Pin No.

(10-Pin MSOP)

Symbol

Description

1VDET

Detected input voltage. VDET and VIN can be connected together.

2VIN

Power supply input.

3

GND

Ground terminal.

4

SELECT

Tri-state input for setting VOUT1 and VOUT2. SELECT = GND for VOUT1 =VOUT2 =2.5V,

SELECT = VIN for VOUT1 =VOUT2 = 3.0V and SELECT = No connect for VOUT1 =VOUT2 =2.8V.

5

SHDN1

Shutdown control input for VOUT1. Regulator 1 is fully enabled when a logic high is applied to

this input. Regulator 1 enters shutdown when a logic low is applied to this input. During

shutdown, regulator output voltage falls to zero, RESET output remains valid.

6

SHDN2

Shutdown control input for VOUT2. Regulator 2 is fully enabled when a logic high is applied to

this input. Regulator 2 enters shutdown when a logic low is applied to this input. During

shutdown, regulator output voltage falls to zero, RESET output remains valid.

7

Bypass

Reference bypass input. Connecting a 0.01

µF to this input further reduces output noise.

8VOUT1

Regulated voltage output 1.

9VOUT2

Regulated voltage output 2.

10

RESET

RESET Output. RESET =Low when VDET is below the Reset Threshold Voltage.

RESET = HighwhenVDET is above the Reset Threshold Voltage.
