ILE4267
5-V Low-Drop Voltage Regulator
Functional Description
ILE 4267 is a 5-V low-drop voltage regulator. It
supplies an output current of > 400 mA. The IC is
shortcircuit-proof and incorporates temperature
protection that disables the 1C at overtemperature
Features
• Output voltage tolerance ≤ ± 2 %
• 400 mA output current capability
• Low-drop voltage
• Very low standby current consumption
• Input voltage up to 40 V
• Overvoltage protection up to 60 V (≤ 400 ms)
• Reset function down to 1 V output voltage
• ESD protection up to 2000 V
• Adjustable reset time
• On/off logic
• Overtemperature protection
• Reverse polarity protection
• Short-circuit proof
• Wide temperature range
• Suitable for use in automotive electronics
Application
The IC regulates an input voltage V, in the range 5.5 V < Vi < 40 V to VQrated = 5.0 V. A
reset signal is generated for an output voltage VQ of < 4.5 V. The reset delay can be set
with an external capacitor. The device has two logic inputs. It is turned-ON by a voltage of
> 4 V on E2 by the ignition for example. It remains active as a function of the voltage on
E6, even if the voltage on E2 goes Low. This makes it possible 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 Ci is necessary for compensation 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 Ci. 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
