  • Forum Post: TPS7A4901 - Adjustable Resistor Selection

    Alex Behnaz
    Hello All, I am designing with the TPS7A4901. I need to make a system that uses standard 5% or 1% SMT resistors to provide a 5V supply line. It does not have to be extremely accurate, just very close. Looking at page 3 of the evaluation kit guide (http://www.ti.com/lit/ug/slvu405/slvu405.pdf), some...

  • Forum Post: LM2941QML Minimum output Voltage

    Wayne Sanderson
    The LM2941QML, adjustable voltage regulator, has a rated minimum output voltage of +5V, however, the adjustment voltage is +1.2V. Anyone have experience running this voltage regulator below the minimum?

  • Forum Post: Value of Cfb for TPS71501

    Dennis Saputelli
    Hello in the data sheet for TPS71501 the figure for the adjustable version shows a capacitor across the feedback resistor, CFB, but gives no guidance for selecting a value can you help please ? my feedback resistor is 1.86M and resistor to ground is 1.00M (3.45Vo) i need to use the adjustable...

  • Forum Post: LM350T adjusting multiple regulators with single control

    Kevin Marcy
    I am using several LM350T voltage regulators in a power supply circuit as shown on page 11 of the data sheet. The goal was to have 7 independent outputs, all at the same voltage adjusted by 1 pot. What seems to be happening is if one of the outputs encounters a heavy load/short circuit, all of the outputs...

  • Forum Post: LM1084 Adjustment pin bypass capacitor ?

    John Klingelhoeffer
    I've built a simple linear regulator power supply using the LM1084ADJ. The input is 16 volts, the output is 13.4 volts, and the load is about 1 ampere. It works just fine with an unbypassed ADJ pin, but if I put any capacitor even close to what is recommended on the data sheet (10-200 uF), the regulator...

  • Forum Post: LM2941 LDO Regulator output capacitor ESR

    Robert E
    Hello, I need a little info so I decided to join the forum and give it a shot. To maintain a stable output the LM2941 regulator gives very specific ESR values for the 22uF+ output capacitor. My question is, ESR at what frequency? 100kHz as listed on most cap datasheets? or some other, ripple frequency...
