HT7533 can be used for STM32F105RBT6 power supply?

Many engineers I know use HT7533 as power supply for STM32F105RBT6 in automotive boards. I looked up the specs, and found that HT7533 is only rated for 100mA. Is it too low for STM32F105RBT6? Is TI's TPS7B91 or TPS7B92 better in this case? Thank you.
