The REF32xx does not require a load capacitor and is stable with any capacitive load. Figure 2 shows typical
connections required for operation of the REF32xx. A supply bypass capacitor of 0.47
F is recommended.
Figure 2. Typical Operating Connections for the REF3225
The REF32xx family of references features an extremely low dropout voltage. With the exception of the
REF3212, which has a minimum supply requirement of 1.8 V, these references can be operated with a supply of
only 5 mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage
versus load is shown in the Typical Characteristic curves.
The REF32xx also features a low quiescent current of 100
A, with a maximum quiescent current over
temperature of just 135
A. The quiescent current typically changes less than 2 A over the entire supply range,
as shown in Figure 3.
Figure 3. Supply Current vs Supply Voltage
Supply voltages below the specified levels can cause the REF32xx to momentarily draw currents greater than
the typical quiescent current. This momentary current draw can be prevented by using a power supply with a fast
rising edge and low output impedance.
The REF32xx can be placed in a low-power mode by pulling the ENABLE/SHUTDOWN pin low. When in
shutdown mode the output of the REF32xx becomes a resistive load to ground. The value of the load depends
on the model, and ranges from approximately 100 k
to 400 k.
