Low Voltage Input LDO Voltage Regulator with Soft-Start Function

■GENERAL DESCRIPTION

The XC6601 series is a low voltage input CMOS LDO regulator which provides highly accurate (±20mV) outputs and can

supply current efficiently due to its ultra low on-resistance even at low output voltages. The series is ideally suited to the

applications which require very low dropout voltage operation and consists of a voltage reference, an error amplifier, a driver

transistor, a current limiter, a fold back circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit,

soft-start circuit and a phase compensation circuit.

Output voltage is selectable in 0.05V increments within a range of 0.7V to 1.8V using laser trimming technology and ceramic

capacitors can be used for the output stabilization capacitor (C_L).

The over current protection circuit (the current limiter and the fold back circuit) as well as the thermal shutdown circuit (the

TSD circuit) are built-in. These two protection circuits will operate when either the output current reaches the current limit

level or the junction temperature reaches the temperature limit level.

With the built-in UVLO function, the regulator output is forced OFF when the voltage level at the VBIAS pin or the VIN pin falls

below the UVLO voltage level. With the soft-start function, the inrush current from V_INto V_OUTfor charging C_Lat start-up can

be reduced and makes the V_INstable.

The CE function enables the output to be turned off and the series to be put in 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

(C_L) to be discharged via the internal auto-discharge switch which is located between the V_OUTpin and the V_SSpin. As a

result the V_OUTpin quickly returns to the V_SSlevel.
