SNAS795A February 2020 – July 2020 REF4132-Q1
PRODUCTION DATA.
The REF4132-Q1 voltage reference features an extremely low dropout voltage. For loaded conditions, a typical dropout voltage versus load is shown on the front page. The REF4132-Q1 features a low quiescent current that is extremely stable over changes in both temperature and supply. The typical room temperature quiescent current is 75 μA, and the maximum quiescent current over temperature is just 100 μA. Supply voltages below the specified levels can cause the REF4132-Q1 to momentarily draw currents greater than the typical quiescent current. Use a power supply with a fast rising edge and low output impedance to easily prevent this issue.
The supply current vs supply voltage figure is shown in Figure 26.
