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.

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

F capacitor or greater is required on the INPUT,
see Fig. 1b. The 22

a 10

F load capacitor and a 100 nF decoupling capacitor are required on the regulator OUTPUT for stability. The 10
μ
F must have
an effective series resistance of
≤
4

the OUTPUT current will not apply to the full range of input voltage. Power dissipation that would require the EM6152A to work above
the maximum junction temperature (+125°C) must be avoided.
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)
