DESCRIPTION
The TL720M devices are monolithic integrated low-dropout voltage regulators offered in 3-pin TO packages. An
input voltage up to 45 V is regulated to V_OUT of 5 V with 2% tolerance. The devices can drive loads up to 450 mA
and are short-circuit proof. At overtemperature, the TL720M devices are turned off by the incorporated
temperature protection.
The input capacitor (C_IN) compensates for line fluctuation. Using a resistor of approximately 1 Ω in series with C_IN
dampens the oscillation of input inductivity and input capacitance. The output capacitor (C_OUT) stabilizes the
regulation circuit. Stability is specified at C_OUT ≥ 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 via 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
