Functional Description

P-TO220-7-230

TLE 4267 is a 5-V low drop voltage regulator for

automotive applications in the PG-TO220-7 or

PG-DSO-14-30 package. It supplies an output current of

> 400 mA. The IC is shortcircuit-proof and has an

overtemperature protection circuit.

Application

The IC regulates an input voltage V_Iin the range of 5.5 V < V_I< 40 V to a nominal output

voltage of V_Q= 5.0 V. A reset signal is generated for an output voltage of V_Q< V_RT(typ.

4.5 V). The reset delay can be set with an external capacitor. The device has two logic

inputs. A voltage of V_E2> 4.0 V given to the E2-pin (e.g. by ignition) turns the device on.

Depending on the voltage on pin E6 the IC may be hold in active-state even if V_E2goes

to low level. This makes it simple to implement a self-holding circuit without external

components. When the device is turned off, the output voltage drops to 0 V and current

consumption tends towards 0 μA.

Design Notes for External Components

The input capacitor C_Iis necessary for compensation of line influences. The resonant

circuit consisting of lead inductance and input capacitance can be damped by a resistor

of approx. 1 Ω in series with C_I. The output capacitor is necessary for the stability of the

regulating circuit. Stability is guaranteed at values of ≥ 22 μF and an ESR of ≤ 3 Ω within

the operating temperature range.

Circuit 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-saturating of the power element.

The reset output RO is in high-state if the voltage on the delay capacitor C_Dis greater or

equal V_UD. The delay capacitance C_Dis charged with the current I_Dfor output voltages

greater than the reset threshold V_RT. If the output voltage gets lower than V_RTa fast

discharge of the delay capacitor C_Dsets in and as soon as V_CDgets lower than V_LDthe

reset output RO is set to low-level (see Figure 6). The reset delay can be set within wide

range by dimensioning the capacitance of the external capacitor.
