XC6603 Series
ETR03070-001
1A, 0.5V Low Input Voltage, High Speed LDO Regulator （Adjustable Soft-start time with an external component）
GENERAL DESCRIPTION
The XC6603 series is a low voltage input (0.5V) operation and provides high accuracy ±15mV / ±20mV and can supply large
The series is ideally suited to the applications which require high current in low input/output voltages and consists of a N-ch driver transistor, a voltage reference, an error amplifier, a current limiter, a foldback circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit, a soft-start circuit and a phase compensation circuit.
Output voltage is selectable in 0.1V increments within a range of 0.5V to 1.8V using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (C start-up can be reduced and makes the V The inrush current conflicts with the soft-start time, therefore if soft-start is set longer, the inrush current is decreased.
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
) to be discharged via the internal switch. As a result the V

The CE pull-down function keeps the IC to be in stand-by mode even if the CE pin is left open.

<Soft-Start Function>
With the XC6603 (Type A), the inrush current (I
) from VIN to V
RUSH
for charging CL at start-up can be reduced and makes the VIN stable.
OUT
With connecting a soft-start capacitor to the SS pin, rise time of the reference voltage (Vref) is adjusted, then soft-start time can be set freely.
The inrush current conflicts with the soft-start time, so that the inrush current is decreased if the soft-start time is set longer.
Please also note that the inrush current is depended on C
L
. When CL or V
BIAS
is larger, the inrush current becomes larger. Please set

When the SS pin is left open, soft-start circuit will not operate.

■OPERATIONAL DESCRIPTION (Continued)
<Current Limiter, Short-Circuit Protection>
The XC6603 series includes a combination of a fixed current limiter circuit and a foldback short-circuit protection. When the output current
reaches the current limit, the output voltage drops and this operation makes the output current foldback to be decreased.
<Thermal Shutdown Circuit (TSD) >
When the junction temperature of the built-in driver transistor reaches the temperature limit, 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.
<Under Voltage Lock Out(UVLO)>

<CE Pin>
The XC6603 internal circuitry can be shutdown via the signal to the CE pin. In shutdown mode with CE low level voltage, the V
pulled down to the V
The CE pin has pull-down circuitry so that CE input current flows during IC operation. If the CE pin voltage is taken from V
then logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal
circuitry when medium voltage is input.

■NOTES ON USE
1. For temporary, transitional voltage drop or voltage rising phenomenon, 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 for the V
3. Please wire the C
4. Capacitances of these capacitors (C

5. When it is used in a quite small input / output dropout voltage, output may go into unstable operation. Please test it thoroughly before using
it in production.
