Stresses above these listed maximum ratings may cause

permanent damage 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 oscilla-

tion of the input capacitor and input inductivity. The ESR

value of the capacitor plays a major role regarding the effi-

ciency of the decoupling. It is recommended also to con-

nect 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 22 µF or

bigger. It is specially important to choose a capacitor with

a low ESR value. Tantal 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 volt-

ages or electric fields; however, anti-static precautions

must be taken as for any other CMOS component. Unless

otherwise specified, proper operation can only occur

when all terminal voltages are kept within the supply volt-

age range. Unused inputs must always be tied to a de-

fined logic voltage level.

the PCB’s structure. 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 Fig. 22).
