Notes:

1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.

Changes in output voltage due to heating effects must be taken into account separately.

2. If not tested, shall be guaranteed to the specified limits.

3. The • denotes the specifications which apply over the full operating temperature range.

STANDARD APPLICATION

3.5

* 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.

VOUT = 1.25 V (1 + RR21) + IADJ R2

Since I ADJ is controlled to less than 100 µA, the

error associated with this term is negligible in

most applications.
