(Can be used with low ESR Capacitor Compatible. ON-OFF Switch) High Speed LDO Regulators

Series

257

3

The XC6204 series are highly precise, low noise, positive voltage LDO

regulators manufactured using CMOS processes. The series achieves

high ripple rejection and low dropout and consists of a standard voltage

source, an error correction, current limiter and a phase compensation

circuit plus a driver transistor.

Output voltage is selectable in 50mV increments within a range of 1.8V ~

6.0V.

The series is also compatible with low ESR ceramic capacitors which

give added output stability. This stability can be maintained even during

load fluctuations due to the excellent transient response of the series.

The current limiter's foldback circuit also operates as a short protect for

the output current limiter and the output pin.

The CE function enables the output to be turned off, resulting in greatly

reduced power consumption.
