Texas Instruments  TL720M05QPWPRQ1

The TL720M05-Q1 devices are monolithic integrated low-dropout voltage regulators offered in 3-pin TO packages. They regulate an input voltage up to 45 V to VOUT of 5 V with 2% tolerance. The devices can drive loads up to 450 mA and are short-circuit proof. At overtemperature, the incorporated temperature protection turns off the TL720M05-Q1 devices.

The input capacitor (CIN) compensates for line fluctuation. Using a resistor of approximately 1 Ω in series with CIN dampens the oscillation of input inductivity and input capacitance. The output capacitor (COUT) stabilizes the regulation circuit. Output is stable at COUT ≥ 22 µF and ESR ≤ 5 Ω, within the operating temperature range.

The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives the base of the series transistor through a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The device also incorporates a number of internal circuits for protection against:

  • Overload
  • Overtemperature
  • Reverse polarity
