Stresses above these listed maximum ratings may
cause permanent damage to the device. Exposure be-
yond specified operating conditions may affect device
reliability or cause malfunction.
Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however, anti-static precau-
tions should be taken as for any other CMOS compo-
nent. Unless otherwise specified, proper operation can
only occur when all terminal voltages are kept within the
supply voltage range. At any time, all inputs must be tied
to a defined logic voltage level.

Table 2
1)
The maximum operating temperature is confimed by
sampling at initial device qualification. In production, all
devices are tested at +85 °C.
2) Full operation quaranteed. To achieve the load regulation
specified in Table 3 a 22 µF capacitor or greater is required
on the INPUT, see Fig. 8. The 22 µF must have an effective
resistance ≤ 5 Ω and a resonant frequency above 500 kHz.
3) A 10 µF load capacitor and a 100 nF decoupling capacitor
are required on the regulator OUTPUT for stability. The
10 µF must have an effective series resistance of ≤ 5 Ω and
a resonant frequency above 500 kHz.
4) RES must be pulled up externally to VOUTPUT even if it is
unused. (Note: RES and EN are used as inputs by EM
test).
5) The OUTPUT current will not apply for all possible
combinations of input voltage and output current.
Combinations that would require the A6155 to work above
the maximum junction temperature (+85 °C) must be
avoided.
6) The thermal resistance specified assumes the package is
soldered to a PCB.
