Datasheet - Electrical Characteristics

6 Electrical Characteristics

VIN = +1.2V, VOUT = +3.0V, VEN = +1.3V, L = 1µH, C1 = C2 = 10µF, typical values @ TAMB = +25ºC (unless otherwise specified). All limits are guar-

anteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality Control) methods.

1. Guaranteed by design and verified in lab characterisation.

2. External Schottky diode is mandatory for output voltages higher than 3V.

3. VOUT is forced to 3.6V in production test.

4. The POK parameters are tested with proprietary test modes. The POK signal is valid from VOUT = 1.9V to 3.0V.
