3 Description
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 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 incorporated temperature
protection turns off the TL720M05-Q1 devices.
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.
Output is stable 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 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
