(XC6209 / XC6212) High Speed LDO Regulator
Description
XC6209/6212 Series
■GENERAL DESCRIPTION
ETR0306-003
High Speed LDO Regulator, Low ESR Cap.
Compatible, Output ON/OFF Control
The XC6209/XC6212 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 voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor.
Output voltage is selectable in 50mV increments within a range of 0.
9V ~ 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.
■APPLICATIONS
●Mobile phones, Cordless phones ●Wireless communication equipment ●Portable games ●Cameras, Video recorders ●Portable AV equipment ●Reference voltage ●Battery powered equipment
