| XC6213 Series Preliminary High Speed LDO Regulators Low ESR Cap. Compatible, Output ON/OFF Control August 12, 2003 V2 Input Voltage Range Output Voltage Range Output Current Low ESR Capacitor Compatible Ultra Small Packages 2.0 ~ 6.0V 2.2 ~ 5.0V Up to 100mA SSOT-24, SOT-25 APPLICATIONS Mobile phones (PDC, GSM, CDMA, IMT2000 etc.) Cordless phones, wireless communication equipment Portable games Cameras, Video recorders Portable AV equipment PDAs GENERAL DESCRIPTION The XC6213 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 100mV increments within a range of 2.2V ~ 5.0V. The series is also compatible with low ESR ceramic capacitors, which give added output stability. 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. Ultra small package, SSOT-24 and SOT-25, are available.
