1. See Figure 2 for connection diagram.

2. Capacitors should be high quality, low ESR components —

solid tantalum is recommended.

Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.

Notes

1. External capacitors required (see Table 2 for specifications).

2. Minimum load required on main output for full power auxiliary operation.
