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
