XC6501A311MR Overview

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

XC6501
■GENERAL
DESCRIPTION
ETR0337-003
Output Capacitor-Less, Low Power Consumption, High Speed LDO Regulator
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 C
L
. 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 C
L
cap is used, the
electric charge stored at C
L
can be discharged via the internal auto-discharge switch and as a result, the V
OUT
pin quickly returns
to the V
SS
level.
The current limit fold-back circuit operates as a short circuit protection and a current limiter function for the output pin.
