Voltage regulation circuit
摘要:
A voltage regulation circuit includes: a first voltage divider that divides a regulation voltage with a predetermined division ratio to generate a division voltage; a first current driving force control unit configured to compare a reference voltage with the division voltage and generate a first control signal; a current driving unit configured to generate a driving current with a variable driving force based on the first control signal and a second control signal, and generate the regulation voltage; and a second current driving force control unit configured to generate the second control signal in accordance with a level variation of the regulation voltage.
