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 VOUT 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 (CIN) compensates for line fluctuation. Using a resistor of approximately 1 ⦠in series with CIN
dampens the oscillation of input inductivity and input capacitance. The output capacitor (COUT) stabilizes the
regulation circuit. Stability is specified at COUT ⥠22 μF and ESR ⤠5 â¦, 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
