• Low-drop voltage

• Reset functionality

• Adjustable reset time

• Suitable for use in automotive electronics

• Integrated overtemperature protection

• Reverse polarity protection

• Wide temperature range

• ESD protection > 4000 V

Functional Description

This device is a 5-V low drop fixed-voltage regulator.

The maximum input voltage is 42

V (65 V, ≤ 400 ms). Up

to an input voltage of 26

V and for an output current up

to 650

mA it regulates the output voltage within a 2%

accuracy. The short circuit protection limits the output

current of more than 650

mA. The device incorporates

overvoltage protection and a temperature protection

which turns off the device at high temperatures.

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 a series transistor via a buffer. Saturation control as a function of the load

current prevents any over-saturation of the power element.

The IC also incorporates a number of internal circuits for protection against:

•Overload

• Overvoltage

• Overtemperature

• Reverse polarity

Application Description

The IC regulates an input voltage in the range of 5.5 V < V

< 36 V to V

Q,nom

= 5.0 V. Up

to 26

V it produces a regulated output current of more than 650 mA. Above 26 V the

save-operating-area protection allows operation up to 36

V with a regulated output

current of more than 300

mA. Overvoltage protection limits operation at 42 V. The

overvoltage protection hysteresis restores operation if the input voltage has dropped

below 36

V. A reset signal is generated for an output voltage of V

< 4.5 V. The delay for

power-on reset can be set externally with a capacitor.
