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. 3 EN 1 VOUT 2 ADJ 4 NC 6 VIN 5 GND ADP7182 TOP VIEW (Not to Scale) EXPOSED PAD NOTES 1.

Figure 7. 6-Lead LFCSP Pin Configuration, Fixed Output Voltage Figure 8. 6-Lead LFCSP Pin Configuration, Adjustable Output Voltage Table 7. 6-Lead LFCSP Pin Function Descriptions LFCSP Pin No. Mnemonic Description Fixed Output Voltage Adjustable Output Voltage 1 1 VOUT Regulated Output Voltage. Bypass VOUT to GND with a 2.2 µF or greater capacitor. Not applicable 2 ADJ Adjustable Input. An external resistor divider sets the output voltage. 3 3 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. 2, 4 4 NC No Connect. Do not connect to this pin. 5 5 GND Ground. 6 6 VIN Regulator Input Supply. Bypass VIN to GND with a 2.2 µF or greater capacitor. 7 7 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. |
