XC6222 Series
ETR0344-006
700mA High Speed LDO Regulator
■GENERAL DESCRIPTION
The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed
voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal
protection circuit, and a phase compensation circuit.
The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this
stand-by mode, the electric charge at the output capacitor (C
a result the VOUT pin will quickly return to the VSS level.
Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output
current reaches the current limit level or junction temperature reaches the temperature limit.

■OPERATIONAL EXPLANATION
The voltage divided by two resistors R1 and R2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT
pin is controlled and stabilized by a system of negative feedback. The current limit and short protection operate in relation to
the level of output current. The thermal protection operates in relation to the level of heat generation. The reverse current
protection operates when V

use a capacitor which does not depend on bias or temperature too much. For a stable power input, please connect an input
capacitor C

The XC6222 series includes reverse current protection to prevent the damage to any connected products such as batteries as a
result of current flow from the V
