Output Capacitor-Less, Low Power Consumption, High Speed LDO Regulator

■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.

The CE function enables the circuit to be put into stand-by mode by inputting a low level signal to the CE pin thereby reducing

current consumption from an already low 13μA (in operation) to less than 0.1μA. In the stand-by mode, if a CL cap is used, the

electric charge stored at CL can be discharged via the internal auto-discharge switch and as a result, the VOUT pin quickly returns

to the VSS level.

The current limit fold-back circuit operates as a short circuit protection and a current limiter function for the output pin.
