XC6601 Series
ETR0335_002
Low Voltage Input LDO Voltage Regulators
Preliminary
www.datGashEeeNt4uE.cRomAL DESCRIPTION
The XC6601 series is a CMOS LDO voltage regulator with precise ( 20mV) outputs which enables the operation in ultra low
On resistance even where low output voltages to achieve high efficiency of the output current. The series is suited for the
application which requires low dropout voltage operation. The series consists of a voltage reference, an error amplifier, a driver
transistor, a current limiter, a fold back circuit, a thermal shutdown (TSD) circuit, a Under Voltage Lock Out (U.V.L.O.) and a
phase compensation circuit.
The output voltage is selectable in 50mV increments within the range of 0.7V to 1.8V using laser trimming technologies. The
output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors.
The over current protection circuit (the current limiter and the fold back circuit) and the thermal shutdown circuit (the TSD
circuit) are built-in. These two protection circuits will operate when the output current reaches limit level or the junction
temperature reaches temperature limit level.
With the built-in U.V.L.O. function, the regulator output is forced OFF when the VBIAS pin or the VIN pin becomes the U.V.L.O.
voltage or lower.
The CE function enables the output to be turned off and the series becomes a stand-by mode resulting in greatly reduced
power consumption. At the time of entering the stand-by mode, the series enables the electric charge at the output capacitor
(CL) to be discharged via the internal auto-discharge switch placed between the VOUT pin and the VSS pin, as a result the VOUT
pin quickly returns to the VSS level.
