What's the best way to make sure I have a known VCC on a battery powered device?

Essentially, you have the choice between switching regulators and linear regulators with LDOs being just a flavor of linear regulators. If efficiency is a concern, you maybe want to use a switching ...

SGM2052 LDO Vbias pin connection

It's a NMOS LDO: Let's look at the curves. Dropout voltage (between VIN and VOUT) can be very low as the left graph shows. But the NMOS gate needs to be biased to a voltage above VOUT, which is ...

SGM2052 LDO Vbias pin connection

What I understood from the datasheet is we need to connect a separate voltage at BIAS pin. Yes. Block diagrams on p.9 clearly show that the BIAS pin is the supply voltage of the internal error ...

Effect of source/input impedance on LDO regulator stability

While I haven't delved much into this, I feel that the problem LDO regulators have with stability is related to the gain of the pass element being highly variable in a common source setup (below right,...
