Regulator

DESCRIPTION

The SCI7810Y series products are the fixed type posi-

tive voltage regulators being developed utilizing the

CMOS silicon gate process. It is mainly consisted of

the reference voltage circuit driven with low operating

current, differential amplifier, transistor for output con-

trol and voltage setting resistor.

Output voltage is fixed on ICs. A wide variety of stan-

dard voltage products are prepared.

The package used is the SOT89-3 pins plastic package.

FEATURES

• A wide variety of lineups: 12 types are offered in the

range of 2V to 6V.

• Low operating current: Typ. 1.5 µA (V

DD = 5.0V).

• Smaller difference between the input and output volt-

age: Typ. 0.02V (I

O = 10 mA, VO = 5.0V).

• Built-in, highly stable reference voltage source: Typ.

1.0V.

• Smaller temperature factor on output voltage: Typ. –

100 ppm/°C.

• Wider operating voltage range: Maximum 15V.
