Description
The OPTIREG™ Linear TLE4262 is a 5 V low drop voltage regulator in a PG-DSO-14 SMD package. The maximum
input voltage is 45 V. The maximum output current is more than 200 mA. The IC is short-circuit proof and
includes a temperature protection which turns off the IC at overtemperature.
The IC regulates an input voltage VI in the range of 6 V < VI < 45 V to VQ,nom = 5.0 V. A reset signal is generated for
an output voltage of VQ,rt < 4.5 V. This voltage threshold can be decreased to 3.5 V by external connection of a
voltage divider. The reset delay can be set externally with a capacitor. The IC can be switched off via the inhibit
input, which reduces the current consumption from 900 µA to typical 0 µA.

5 V low drop voltage regulator
Functional description

Functional description
The control amplifier compares a reference voltage, which is kept highly accurate by resistance adjustment,
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 over-saturation of the power element. If the
externally scaled down output voltage at the reset threshold input drops below 1.35 V, the external reset delay
capacitor is discharged by the reset generator. If the voltage on the capacitor reaches the lower threshold VDRL,
a reset signal is issued on the reset output and not cancelled again until the upper threshold VDU is exceeded.
If the reset threshold input is connected to GND, reset is triggered at an output voltage of 4.5 V. The IC can be
switched at the TTL-compatible, low-active inhibit input. It also includes a number of internal circuits for
protection against:
•
Overload
•
Overtemperature
•
Reverse polarity
4.1
Choosing 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 circuit consisting of input inductivity and input capacitance can be damped. The output
capacitor is necessary for the stability of the regulating circuit. Stability is ensured at values CQ ≥ 22 µF and an
ESR of ≤ 3 Ω within the operating temperature range. For small tolerances of the reset delay the spread of the
capacitance of the delay capacitor and its temperature coefficient should be noted.

The power-on reset delay time is defined by the charging time of an external capacitor CD which can be
calculated as follows:
CD = (∆trd × ID,c) / ∆V
(5.1)
Definitions:
•
CD = delay capacitor
•
∆trd = delay time
•
ID,c = charge current, typical 10 µA
•
∆V = VDU, typical 1.8 V
•
VDU = upper delay switching threshold at CD for reset delay time
