Unit : (mm)
Standard Application Circuit
A common ground is required between the input and the
output voltages. The input voltage must remain typically
2.0V above the output voltage even during the low point on
the Input ripple voltage.
XX = these two digits of the type number indicate voltage.
* = Cin is required if regulator is located an appreciable
distance from power supply filter.
** = Co is not needed for stability; however, it does improve
transient response.
Absolute Maximum Rating (Ta = 25oC unless otherwise noted)

Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as
possible, and thermal effects must be taken into account separately.
This specification applies only for DC power dissipation permitted by absolute maximum ratings.
