EXPOSED PAD
NOTES
1. NC = NO CONNECT. DO NOT CONNECT TO THIS PIN.
2. THE EXPOSED PAD ON THE BOTTOM OF THE LFCSP PACKAGE ENHANCES
THERMAL PERFORMANCE AND IS ELECTRICALLY CONNECTED TO VIN
INSIDE THE PACKAGE. THE EXPOSED PAD MUST BE CONNECTED TO THE
VIN PLANE ON THE BOARD FOR PROPER OPERATION. BECAUSE THIS IS A
NEGATIVE VOLTAGE REGULATOR, VIN IS THE MOST NEGATIVE POTENTIAL
IN THE CIRCUIT.

VOUT
Regulated Output Voltage. Bypass VOUT to GND with a 2.2 µF or
greater capacitor.
Not applicable

ADJ
Adjustable Input. An external resistor divider sets the output voltage.

EN
Drive EN 2 V above or below ground to enable the regulator, or drive
EN to ground to turn off the regulator. For automatic startup,
connect EN to VIN.

Regulator Input Supply. Bypass VIN to GND with a 2.2 µF or greater
capacitor.

EPAD
Exposed pad. The exposed pad on the bottom of the LFCSP package
enhances thermal performance and is electrically connected to VIN
inside the package. The exposed pad must be connected to the VIN
plane on the board for proper operation. Because this is a negative
voltage regulator, VIN is the most negative potential in the circuit.
