Notes: 1. Rated voltages are with reference to the GND terminal.

2. For rated currents, inflow to the IC is indicated by (+), and outflow by (–).

3. Shows the transient current when driving a capacitive load.

4. In case of R2A20113DD (DILP):

θja = 120°C/W

In case of R2A20113SP (SOP):

θja = 120°C/W

This value is a thing mounting on 40

× 40 × 1.6 [mm], a glass epoxy board of wiring density 10%.
