Linear voltage regulator generating sub-reference output voltages |
摘要 |
A linear voltage regulator includes a pair of amplifiers. A first amplifier of the pair is used in conventional fashion to generate a regulated output voltage by controlling an impedance of a pass transistor in the linear voltage regulator, the controlling being based on a difference between a reference voltage and a voltage at a first node in a voltage divider network connected between the output terminal of the voltage regulator and a ground terminal. The second amplifier of the pair compares the regulated output voltage and a voltage at a second node in the voltage divider network, and injects a proportional current into the first node. Generation of a regulated output voltage lesser than the reference voltage is thereby enabled.
