XC6601 Series

ETR0335_006

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
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 V
below the UVLO voltage level. With the soft-start function, the inrush current from V
be reduced and makes the V
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

) to be discharged via the internal auto-discharge switch which is located between the V

<Voltage Regulator>
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The N-channel

BIAS

the V

pin supplies output current also. VIN pin is connected to a driver transistor and provides output current.

BIAS

In order to obtain high efficient output current through low on-resistance, please take enough Vgs (=V
transistor. Output current triggers operation of constant current limiter and fold-back circuit, heat generation triggers operation of
thermal shutdown circuit, the driver transistor circuit is forced OFF when V
Further, the IC's internal circuitry can be shutdown via the CE pin's signal.

<Low ESR Capacitor>
With the XC6601 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation
circuit is built-in. The output capacitor (C
compensation. Values required for the phase compensation are as the table below.
For a stable power input, please connect an bias capacitor (C
connect an input capacitor (CIN) of 1.0μF between the VIN pin and the VSS pin. In order to ensure the stable phase
compensation while avoiding run-out of values, please use the capacitor (C

CL High Speed Auto-Discharge>

XC6601 series can quickly discharge the electric charge at the output capacitor (C
enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the V
pin. When the IC is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it could avoids malfunction.
At that time, CL discharge resistance is depended on a bias voltage. Discharge time of the output capacitor (C
auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R]
and an output capacitor value (CL) as τ(τ=C x R), the output voltage after discharge via the N channel transistor is calculated
by the following formulas.

V = V

V : Output voltage after discharge, V

<Current Limit, Short-Circuit Protection>
The XC6601 series’ fold-back circuit operates as an output current limiter and a short protection of the output pin. When the load
current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output pin is
shorted to the V

<Thermal Shutdown Circuit (TSD) >
When the junction temperature of the built-in driver transistor reaches the temperature limit level (150℃ TYP.), the thermal
shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown
function is released and the IC’s operation is automatically restored because the junction temperature drops to the level of the
thermal shutdown release temperature (125℃ TYP.).

<CE Pin>
The IC internal circuitry can be shutdown via the signal from the CE pin with the XC6601 series. In shutdown mode, output at the
V

pin will be pulled down to the VSS level via R1 & R2. However, as for the XC6601 series, the CL auto-discharge resistor is

The CE pin of XC6601A has pull-down circuitry so that CE input current increase during IC operation. The CE pin of XC6601B
does not have pull-down circuitry so that logic is not fixed when the CE pin is open. If the CE pin voltage is taken from V

■NOTE ON USE

1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be

exceeded.

2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output

current. Please keep the resistance low between V
