XC6501集成电路（IC）的线性+开关稳压器规格书PDF中文资料

■ GENERAL DESCRIPTION

The XC6501 series is a 6.0V high speed, low noise CMOS LDO regulator that can provide stable output voltages within a range of 1.2V to 5.0V (0.05V increments) even without a load capacitor CL. This is possible because phase compensation is carried out internally unlike other LDOs where it is done externally. The series consists of a reference voltage source, driver transistor, error amplifier, current limit circuit, and phase compensation circuit.
