LOW-DROP-OUTPUT TYPE VOLTAGE REGULATOR AND RF SWITCHING CONTROL DEVICE HAVING THE SAME |
| 摘要 |
A low-drop-output type voltage regulator may include an error amplifier providing a gate signal depending on a voltage difference between a reference voltage and a feedback voltage, a semiconductor switch adjusting a current between an input terminal receiving a battery voltage and a ground, in response to the gate signal, a feedback circuit dividing and detecting a detection voltage in a detection node between the semiconductor switch and the ground and providing the feedback voltage, a voltage sensor sensing the battery voltage, and a feedback voltage controller adjusting a level of the feedback voltage depending on the sensed battery voltage. |

1. A low-drop-output type voltage regulator comprising:
an error amplifier configured to provide a gate signal depending on a voltage difference between a reference voltage and a feedback voltage; a semiconductor switch configured to adjust a current between an input terminal receiving a battery voltage in response to the gate signal and a ground; a feedback circuit configured to divide and detect a detection voltage in a detection node between the semiconductor switch and the ground and providing the feedback voltage; a voltage sensor configured to sense the battery voltage; and a feedback voltage controller configured to adjust a level of the feedback voltage depending on the sensed battery voltage. |
