Note 1. Specification refers to Typical Application Circuit.
Note 2. This device is ESD sensitive. Use of standard ESD handling precautions is required.
Note 3. Abnormal condition; Ex: over-current, output over-voltage, under-voltage lockout, soft-start disappear.
Note 4. VCC pin should not be used to externally source current. It is not short protected.
