Part Number: LP3988 When I look at the Absolute Maximums section, it says that PD must be the lesser of VIN + 0.3 V or 6 V.
Is actually this correct? This seems unusual for an open-drain power-good output, that it can't go above the input rail.
Other Parts Discussed in Thread: LP3988 Hi,
I am going to use the LP3988 device for my new design. In LP3988 datasheet, they have given the output capacitance is 1uf(typ) to 20uf(max).
My question is,the output rail capacitance(including other device…

Part Number: BQ2970 Other Parts Discussed in Thread: TIDA-00669 , LP3988 , TPS63051 I made a test board by TIDA-00669 schematic.
I measured the voltage and got V_ab :-2.8 , V_ac : 1.15, V_bc : 3.95.
I connected a regulator lp3988 at point d and…
No, the LP3988 R1 and R2 values are not available.
If I guess that 50% of the typical Iq(no load) current ((85uA / 2)= 42uA) is through R1 and R2, AND if I guess that typical Vref is 1.250V, then R2 would need to be about 30.0k ohms, which would make…
PG pin is disabled (off / hi-z) when Ven is low.
Following three images are scope shots where LP3988 PG pin is biased from Vin (5V) thru a 50k ohm pull-up R, while EN pin is toggled.
