UNIT

VCNTL Supply Voltage (Note 1)

VCNTL

3.1 ~ 6

VIN Supply Voltage (Note 2)

VIN

1.2 ~ 3.5

VREF Input Voltage

VREF

0.85 ~ 1.75

VOUT Output Voltage (Note 3)

VOUT

VREF ± 0.02

VOUT Output Current (Note 4,5)

IOUT

-3 ~ +3

Junction Temperature

0 ~ +125

°C

Note: 1. Please always keep VCNTL-VOUT>1.9V for good regulation.

2. Please supply enough voltage to VIN for sourcing desired maximum output current. Please refer to the VIN

Dropout Voltage vs. Output Current in the Typical Characteristics.

3. The VOUT is regulated to the VREF with additional voltage offset and load regulation except over-load

conditions.

4. The symbol “+” means the VOUT sources current to load; the symbol “-“ means the VOUT sinks current to

GND.

5. The max. IOUT varies with the TJ and the voltages of VIN-VOUT and VOUT. Please refer to the Typical

Characteristics.
