    TPS723: Recommended evaluation board, MULTIPKGLDOEVM-823, has incorrect wiring for this regulator

    TI Thinks Resolved
    Part Number: TPS723 The TI website recommends the MULTIPKGLDOEVM-823 for this regulator. The regulator package is SOT23, DBV. However, the input pin on the board layout is pin 1 and the ground pin is pin 2. But this regulator input pin is pin 2, and the...

    RE: TLV743P: Drop out Voltage and Load Transient @ 2.5V

    Hi Ishaan, You are correct, per our Electrical Characteristics table, the maximum dropout over the full temperature range is 290 mV. Transient performance will depend on application specific conditions such as the output capacitor and the magnitude...

    RE: TLV757P: Maximum Cout ESR value

    Hi Satoshi, TLV757P was designed, tested, and characterized for operation with ceramic capacitors which have low ESR. How much ESR are you anticipating in your application? You are correct that the best method to validate your intended output capacitors...

    RE: TLV702: instability of the LDO with higher capacitance on the output

    Hi Bart, The LDO output being higher than its regulation voltage indicates that either a higher voltage rail is leaking onto the LDO output rail or that the LDO itself is damaged. The most telling scopeshot is your last scopeshot where you have isolated...

    RE: TPS763-Q1: Vout Deviation at Vout = 5.7V

    Hi Paul, While it is possible to have an output voltage above 5 V for the adjustable device, the TPS763-Q1 family is only tested and specified for a maximum output voltage of 5 V. While the maximum dropout is not specified for a 5.7 V output, if you...

    RE: LP2985LV-N: Minimum load current for stable operation

    Hi Stani, Could you confirm that your additional question is about LP2985LV-N? This family of devices does not have a 3.3 V output option. If LP2985LV-N the datasheet shows the transient response for a 1.8 V output which will be similar to the 1...

    RE: TLV755P: IC MARKING CODE MISSING FOR DEVICE PTLV75528PDBVR

    Hi Abhishek / Aswath, Do you still have the multimeter connected when you took the second measurement? It would be normal to have a drop on the order of 15mV as you scale the load to 250mA, but 200mV seems really high. Are you testing the LDO on an...

    RE: TINA/Spice/LP3985: TINA model for LP3985 2.5V

    Hi Mauro, We do not have a model for LP2985 available and have no plans of releasing one for this older device. Both the LP2985 and TLV713 datasheets contain startup curves. TLV713 is only offered in fixed output versions and does not have an NR pin...
