BIPOLAR ANALOG INTEGRATED CIRCUIT

µPC1945

ADJUSTABLE PRECISION SHUNT REGULATORS

DESCRIPTION

The µ PC1945 is an adjustable-shunt regulator featuring a high-precision internal reference voltage. The separate

power supply pin (V^CCpin) allows the cathode voltage to be dropped to as low as 0.4V, making this product ideal for

error amplifiers that use a low voltage (minimum 1.8 V) output switching regulator.

Support for high-density mounting is also provided through the use of a 5-pin plastic mini-moldpackage.

FEATURES

• Separate cathode and power supply pins

• Suitable for low voltage (minimum 1.8 V) output switching regulator

Cathode voltage range: 0.4 V to 5 V

Power supply voltage range: V^REFto 5 V

Reference voltage: 1.26 V

• 5-pin plastic mini-mold package

Mold dimensions: 2.9 mm(L)×1.5 mm(W)×1.1 mm(H)
