The transient response for a 0.5V step on VIN with and The LTC6652 voltage references do not require an input without an output capacitor is shown in Figures 2 and 3, capacitor, but a 0.1µF capacitor located close to the part respectively. improves power supply rejection. The LTC6652 references with an output of 2.5V and above The LTC6652 voltage references are stable with or without are guaranteed to source and sink 5mA. The 1.25V and a capacitive load. For applications where an output capaci- 2.048V versions are guaranteed to source 5mA and sink tor is beneficial, a value of 0.1µF to 10µF is recommended 1mA. The test circuit for transient load step response is depending on load conditions. The Typical Performance shown in Figure 1. Figures 4 and 5 show a 5mA source Characteristics section includes a plot illustrating a region and sink load step response without a load capacitor, of marginal stability.
