请教下版主,stm8L15xxx内部volt regulator是否就是LDO(输出1.8V)?
那么如果我外部用锂电(4.2V)给Vdd供电,使用dcdc降压,虽然纹波大,但是有内部电压调整器,纹波是否可以大幅下降?
用dcdc不直接用LDO的原因是想高效一点。谢谢指点!
The STM8L15xxx embeds an internal voltage regulator for generating the 1.8 V power
supply for the core and peripherals. This regulator has two different modes:
● Main voltage regulator mode (MVR) for Run, Wait for interrupt (WFI) and Wait for event
(WFE) modes.
● Low power voltage regulator mode (LPVR) for Halt, Active-halt, Low power run and Low power
wait modes.
