8 / 23 page ![]() Data Sheet ADPL44002 analog.com Rev. 0 8 of 23 PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS Figure 3. 6-Lead LFCSP Pin Configuration Figure 4. 5-Lead TSOT Pin Configuration Pin Descriptions Table 5. Pin Descriptions PIN NAME DESCRIPTION 6-LEAD LFCSP 5-LEAD TSOT 1 5 VOUT Regulated Output Voltage. Bypass VOUT to GND with a 2.2µF or greater capacitor. 2 4 SENSE/ADJ Sense Input (SENSE). Connect to load. An external resistor divider may also be used to set the output voltage higher than the fixed output voltage (ADJ). 3 2 GND Ground. 4 3 EN The Enable Pin Controls the operation of the LDO. Drive EN high to turn on the regulator. Drive EN low to turn off the regulator. For automatic startup, connect EN to VIN. 5 Not applicable SS Soft Start. An external capacitor connected to this pin determines the soft-start time. Leave this pin open for a typical 400μs start-up time. Do not ground this pin. 6 1 VIN Regulator Input Supply. Bypass VIN to GND with a 2.2µF or greater capacitor. EP Exposed Pad. The exposed pad on the bottom of the package enhances thermal performance and is electrically connected to GND inside the package. It is recommended that the exposed pad connect to the ground plane on the board. 3 GND 1 VOUT 2 SENSE/ADJ 4 EN 6 VIN 5 SS ADPL44002 TOP VIEW (Not to Scale) EXPOSED PAD NOTES 1. THE EXPOSED PAD ON THE BOTTOM OF THE PACKAGE ENHANCES THERMAL PERFORMANCE AND IS ELECTRICALLY CONNECTED TO GND INSIDE THE PACKAGE. IT IS RECOMMENDED THAT THE EXPOSED PAD CONNECT TO THE GROUND PLANE ON THE BOARD. ADPL44002 TOP VIEW (Not to Scale) 1 VIN 2 GND 3 EN 5 VOUT 4 SENSE/ADJ |
