Stresses above these listed maximum ratings may cause

permanent damages to the device. Exposure beyond

specified operating conditions may affect device reliability or

cause malfunction.

Decoupling Methods

The input capacitor is necessary to compensate the line

influences. A resistor of approx. 1

Ω connected in series

with the input capacitor may be used to damp the oscillation

of the input capacitor and input inductance. The ESR value

of the capacitor plays a major role regarding the efficiency of

the decoupling. It is recommended also to connect a

ceramic capacitor (100 nF) directly at the IC's pins. In

general the user must assure that pulses on the input line

have slew rates lower than 1 V/µs. On the output side, the

capacitor is necessary for the stability of the regulation

circuit. The stability is guaranteed for values of 10 µF or

greater. It is especially important to choose a capacitor with

a low ESR value. Tantalum capacitors are recommended.

See the notes related to Table 2. Special care must be

taken in disturbed environments (automotive, proximity of

motors and relays, etc.).

Handling Procedures

This device has built-in protection against high static

voltages or electric fields; however, it is advised that normal

precautions be taken as for any other CMOS component.

Unless otherwise specified, proper operation can only occur

when all terminal voltages are kept within the voltage range.

At any time, all inputs must be tied to a defined logic voltage

level.

Note 5: the thermal resistance specified assumes the package is soldered to a PCB. A typical value of 51°C/W has been obtained with a dual

layer board, with the slug soldered to the heat-sink area of the PCB (See Figure 16)
