SLVSDF7A December 2016 – July 2017 TPSM84A21
The TPSM84A21 requires no external input or output capacitance to operate. Internal to the TPSM84A21 there is 66.1 µF (nominal) of ceramic input capacitance. Additionally, internal to the TPSM84A21 there is 185 µF (nominal) of ceramic output capacitance.
Applications requiring additional ripple voltage reduction should add ceramic input and output capacitors directly at the VIN and VOUT pins of the device. Applications requiring improved transient response can also benefit by adding additonal ceramic or low-ESR bulk output capacitance. See the Capacitance section of the Electrical Characteristics table for more information when adding external input and output capacitors.
