Part Number: TPS7A8300 Hi TI experts,
In our design, there is an uncontrollable high pulse (3.3V) applied to EN pin before normal power up sequence starts.
The pulse width is about ~10ns. Is there any deglitch filter inside TPS7A8300 EN pin which can filter…

Hi TI experts,
For the design of TPS7A8300RGRR, we use external resistors to set output voltage.
The design parameters are as follows, Vbias=5V, Vin=1.2V, Vout=0.9V,and using an external power supply to control the EN of TPS7A…
Part Number: TPS7A8300 Hi TI experts,
How to understand the EN threshold from datasheet? Given EN sweeps from 0<->3.3V:
1. From 0V-3.3V: once EN rises above 1.1V, the LDO turns on, right?
2. From 3.3V->0V: When will LDO be turned off? Below 1.1V…
Part Number: TPS7A8300 Other Parts Discussed in Thread: TPS7A83A Hello Support team,
Customer asks TPS7A8300 Fig 9-2. Fig 9-2 shows "without BIAS", but, the schematic has Bias supply. Is this TYPO? No bias and keeping BIAS pin open is correct information…
Part Number: TPS7A8300 Other Parts Discussed in Thread: TPS7A94 , TPS7A30 , TPS7A33 Hello Team, We are planning to use the regulator TPS7A8300RGRR in one of our applications. The input is a 5.5V from a buck converter (LMR51450SDRRR). The TPS7A8300RGRR is used…
Part Number: TPS7A8300 Hi TI experts,
I used TPS7a8300 in my design to generate A1.8V from A2.5V. There is another power rail P3V3_Z0 which was enabled ~550ms later than A1.8V.
Observed once P3V3_Z0 is enabled (ramped up), A1.8V is bumped up from 1.8V…

PSRR=20log(Ripple input/Ripple output)=20log(Av/Avo)
But why Ripple input/Ripple output=Av/Avo, I don't understand that.
