ADP3301
It is not recommended to use solder mask or silkscreen on the
PCB traces adjacent to the ADP3301’s pins since it will increase

Shutdown Mode
Applying a TTL high signal to the shutdown pin, or tying it to
the input pin, will turn the output ON. Pulling the shutdown
pin low, or tying it to ground, will turn the output OFF. In
shutdown mode, quiescent current is reduced to less than 1 μ A.

range of load, input voltage and temperature conditions. If, for
example, regulation is lost by reducing the supply voltage below
the combined regulated output and dropout voltages, the ERRor
flag will be activated. The ERR output is an open collector,
which will be driven low.
Once set, the ERRor flag’s hysteresis will keep the output low

raising the supply voltage or reducing the load.

APPLICATION CIRCUITS
Crossover Switch
The circuit in Figure 21 shows that two ADP3301s can be used
to form a mixed supply voltage system. The output switches

Output voltages can be any combination of voltages from the

Ordering Guide.
Higher Output Current
The ADP3301 can source up to 100 mA without any heatsink
or pass transistor. If higher current is needed, an appropriate
pass transistor can be used, as in Figure 22, to increase the
output current to 1 A.
Step-Up/Step-Down Post Regulator
The circuit in Figure 23 provides a high precision, low dropout
regulated output voltage. It significantly reduces the ripple from
a switching regulator. The ADP3000 used in this circuit is a
switching regulator in the step-up configuration.
