UPC1945中文资料瑞萨数据手册PDF规格书

DESCRIPTION

The µPC1945 is an adjustable-shunt regulator featuring a high-precision internal reference voltage. The separate power supply pin (VCC pin) allows the cathode voltage to be dropped to as low as 0.4 V, 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-mold package.
