Functional Description
The TLE 4275 is a monolithic integrated low-drop
voltage regulator in a 5-pin TO-package. An input
voltage up to 45 V is regulated to VQ,nom = 5.0 V. The IC
is able to drive loads up to 450 mA and is short-circuit
proof. At overtemperature the TLE 4275 is turned off by
the incorporated temperature protection. A reset signal
is generated for an output voltage VQ,rt of typ. 4.65 V.
The delay time can be programmed by the external
delay capacitor.

TLE 4275
Dimensioning Information on External Components
The input capacitor CI is necessary for compensation of line influences. Using a resistor
of approx. 1 Ω in series with CI, the oscillating of input inductivity and input capacitance
can be damped. The output capacitor CQ is necessary for the stability of the regulation
circuit. Stability is guaranteed at values CQ ≥ 22 µF and an ESR of ≤ 5 Ω within the
operating temperature range.
Circuit Description
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
IC also incorporates a number of internal circuits for protection against:
• Overload
• Overtemperature
• Reverse polarity
