Typical Application Circuit (LDO Configuration)

Assuming a fixed 3.3V output variant of the 8682L, the standard application circuit is:

          +-------------------+
          |                   |
      Vin o---+---[C1]---+----+---- VIN (pin1)
           |   (1uF)     |         |
           +----+--------+         |
                |                  |
               GND                 |
                                   |
          +----+-----------------+ |
          |    |                 | |
          |   EN (pin3) --+      | |
          |               |      | |
          |     GND (pin2)-+-GND | |
          |                     | |
          |   VOUT (pin5)--------+-o--- Vout (3.3V)
          |                     | |
          |                     +---[C2]---+ GND
          |                         (1uF)   |
          +-----------------------------+---+

Component values:

C1 (input capacitor): 1µF to 10µF, ceramic X5R/X7R.
C2 (output capacitor): 1µF to 10µF, ESR < 1Ω.
R1, R2 (if adjustable): Use formula Vout = Vref * (1 + R1/R2), Vref typically 0.6V or 0.8V.

Regulatory and safety notes

RF output power limits and spectral requirements vary by region; configure transmit power and duty cycle to comply with local regulations (e.g., ETSI EN 300 220 for 868 MHz in Europe, FCC Part 15 in the U.S.).
Ensure antenna gain and effective isotropic radiated power (EIRP) remain within legal limits.
