Notes: 1. Dropout voltage (VDROP) is the voltage difference between the input and the output at which the output

voltage drops 2% below its nominal value.

2. Quiescent current (IQ) is the current difference between the input and the output.

3. Short circuit current (ISC) is measured with VOUT pulled to GND.

4. This specification is guaranteed by design.

5. UTC LR9107 has 2 options for output, built-in discharge and non-discharge.

6. Potential multiple grades based on following output voltage accuracy.
