2018 market in 1H has created a challenge for designs in portable electronics. The lead-times for the industry could cause delays in delivery and manufacturing.
LDOs can help alleviate the burden by working with no capacitors!

TLV713P and TLV733P Can work without input and output capacitors

Performance and Space Savings
If the power supply operating frequency is below or at 100KHz the PSRR of the TLV733 can behave very well for easy low current loads. If a higher frequency is needed then a capacitor would be recommended
Having no capacitors in the input/output also saves on space!

SSD controllers and flash cells are very sensitive to voltage swings. Power for the cells and controllers is usually packed in a space constrained board making pkg size very important. LDOs with very low dropdown in 1mm2 are preferred. Ultra-low IQ is also important to maintain regulation without draining the battery. Power good signal is also used for resetting the SSD controller and notifying the PCIE host.
