Positive Supply Voltage Input. Connect this pin to the 3 V supply with a 2.2 μF decoupling capacitor.
Voltage Doubler Output. This was derived by doubling the 3 V supply. A 2.2 μF capacitor to
ground is required on this pin.
Voltage Regulator Input. The user may bypass this circuit by using the LDO_ON/
OFF
pin.
5 V Output. This was derived by doubling and regulating the 3 V supply. A 2.2 μF capacitor
to ground is required on this pin to stabilize the regulator.
5 V Input. This is the input to the voltage tripler and inverter charge pump circuits.
Control Logic Input. 3 V CMOS logic. A logic high selects the internal LDO for regulation of
the 5 V voltage doubler output. A logic low isolates the internal LDO from the rest of the charge
pump circuits. This allows the use of an external LDO to regulate the 5 V voltage doubler
output. The output of this LDO is then fed back into the voltage tripler and inverter circuits of
the ADM8839.
Digital Input. 3 V CMOS logic. Active low shutdown control. This shuts down the timing
generator and enables the discharge circuit to dissipate the charge on the voltage outputs, thus
driving them to 0 V.

.
Connect this pin to GND.
15 V Output. This was derived by tripling the 5 V regulated output. A 0.22 μF capacitor
is required on this pin.
External capacitor C3 is connected between these pins. A 0.22 μF capacitor is recommended.
External capacitor C2 is connected between these pins. A 0.22 μF capacitor is recommended.
External capacitor C4 is connected between these pins. A 0.22 μF capacitor is recommended.
–15 V Output. This was derived by tripling and inverting the 5 V regulated output. A 0.22 μF
capacitor is required on this pin.
Device Ground.
External capacitor C1 is connected between these pins. A 2.2 μF capacitor is recommended.
