TLE 4276
Functional Description
The TLE 4276 is a low-drop voltage regulator in a TO package. The IC regulates an input
voltage up to 40 V to VQ,nom = 5.0 V (V50), 8.5 V (V85), 10 V (V10) and adjustable voltage
(V). The maximum output current is 400 mA. The IC can be switched off via the inhibit
input, which causes the current consumption to drop below 10 µA. The IC is short-circuit-
proof and includes temperature protection which turns off the device at overtemperature.
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 ≤ 3 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

Application Information for Variable Output Regulator TLE 4276 V, SV, DV, GV
The output voltage of the TLE 4276 V can be adjusted between 2.5 V and 20 V by an
external output voltage divider, closing the control loop to the voltage adjust pin VA.
The voltage at pin VA is compared to the internal reference of typical 2.5 V in an error
amplifier. It controls the output voltage.
Figure 5 Application Detail External Components at Output for Variable
Voltage Regulator
The output voltage is calculated according to Equation (1):
VQ = (R1 + R2)/R2 × Vref, neglecting IVA (1)
Vref is typically 2.5 V.
To avoid errors caused by leakage current IVA, we recommend to choose the resistor
value R2 according to Equation (2):
R2 < 50 kΩ(2)
For a 2.5 V output voltage the output pin Q is directly connected to the adjust pin VA.
The accuracy of the resistors R1 and R2 add an additional error to the output voltage
tolerance.
The operation range of the variable TLE 4276 V is VQ + 0.5 V to 40 V. For internal biasing
a minimum input voltage of 4.3 V is required. For output voltages below 4 V the voltage
drop is 4.3 V - VQ
