Voltage regulator has device coupled to signal branch for association with first amplifier input and regulator output for subtracting load compensation voltage from reference voltage

摘要

The device has an operational amplifier, a reference voltage source connected to its differential inputs, a transistor with its control input connected to the amplifier output and its controlled path between a supply voltage pole and the regulator output, a feedback network and a device coupled to a signal branch for association with the first amplifier input and the a output for subtracting a load compensation voltage a from the reference voltage. The device has an operational amplifier with two differential inputs and an output, a reference voltage source connected to both differential inputs, a transistor with its control input connected to the amplifier output and its controlled path between a supply voltage pole and the regulator output, a feedback network between the regulator output and the other amplifier input and a device coupled to the signal branch for association with the first amplifier input and the regulator output for subtracting a compensation voltage corresponding to the load from the reference voltage.
