Low Drop Voltage Regulator
Functional Description

Functional Description
Functional Description
The TLE4276 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), 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:

Functional Description
Application Information for Variable Output Regulator TLE 4276 V
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.

Application Detail External Components at Output for Variable Voltage Regulator
The output voltage is calculated according to Equation (3.1):
VQ = (R1 + R2)/R2 × Vref, neglecting IVA
(3.1)
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 (3.2):
R2 < 50 kΩ
(3.2)
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
