Part Number: LP5912 I'm planning to use the LDO part LP5912-1.8DRVR to generate a 1.8V output using a 2.5V input. From the LP5912 datasheet, I'm able to confirm that we can generate 1.8V using a 2.5V input voltage (VIN = VOUT + 0.5V). However, even though…
Part Number: LP5912 Dear Specialists,
My customer has a same type of question.
I would be grateful if you could advise.

(1) In the reference thread, there is a discussion when Isc exceeds 1100mA at Figure 51. of datasheet P.16.
There is no clear mention…
Part Number: LP5912-Q1 Other Parts Discussed in Thread: LP5907-Q1 , LP5907 , TPS7A21-Q1 , LP5912 Dear team,
It is similar question of e2e below, but it is for LP5912-Q1. https://e2e.ti.com/support/power-management-group/power-management/f/power-management…
Part Number: LP5912-Q1 Other Parts Discussed in Thread: LP5912 Hello E2E Experts,
Good day.
We are using the LP5912Q3.3DRVRQ1 but there are some serious issues. The IC shorts to ground during start up.
Nominal load is less than 100mA. System works fine…
Part Number: LP5912 I have one question.
The LP5912 is used to change a voltage from 3.8V to 1.8V. 1.8V is supplied to the external IC from the LP5912. A maximum rush current of 1.4A flows for 20us when the external IC starts. Is there the LP5912 at risk…
Part Number: LP5912 Hi Team,
If the voltage of the EN pin is more than OFF Threshold and less than ON Threshold(0.3 V < VEN < 1.3 V)
What voltage will VOUT output?
Best Regards, Tom
Part Number: LP5912 Hi ti,
The EN pin of LP5912 is internally pulled low by a 3M resister to GND. Does this 3M pull low resister guarantee the LDO disable when leave EN pin float? Does a additional external pull low resister affect to normal EN pin? …
Part Number: LP5912 Hi ti,
The PG is undefined when VIN is less than 1.6V, you may see on datasheet. You may also see such as fig 3. ,it shows the PG keep low during 0<VIN<1.6V.
Does such a "undefined" mean "can not be high impedance" ?…
Part Number: TLV755P Hello,
I am considering using the TLV75533PDRVR and LP5912-3.3DRVR in the same layout. This is in response to the recent difficulty in obtaining parts. The packages are the same, and the pinouts are generally compatible. Can both devices…
Part Number: LP5912-Q1 Hi Expert,
I see in LP5912-Q1 datasheet that "This device is available with fixed output voltages from 0.8 V to 5.5 V in 25-mV steps.". Does it mean that LP5912-Q1 has 0.8V, 0.825V, 0.05V......5.45V, 5.475V and 5.5V output voltage…
