XC6503 Series
CL Capacitor-Less 500mA Low Power Consumption High Speed LDO Regulator
■GENERAL DESCRIPTION
The XC6503 series is a 500mA high speed CMOS LDO regulator that can provide stable output voltages even without a load
capacitor CL. The devices are available in fixed output voltage from 1.2V to 5.0V in 0.05V increments
The C
capacitor-less is possible because phase compensation is carried out internally unlike other LDOs where it is done
L
externally. It results in saving board design space. The current limit fold-back circuit and thermal shutdown circuit work as
protection circuit. The XC6503P is a 3-Terminal regulator and the XC6503D has a chip enable function, which enables the
entire circuit to be turned off by a low level input signal to the CE pin.

■ OPERATIONAL EXPLANATION
The voltage divided by resistors R1 and R2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET which is connected to the V
V
pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short circuit protection operate
OUT
in relation to the level of output current and heat dissipation. Current limit circuit and short protection circuit operate with output
current and thermal shutdown circuit will operate with heating. Further, the IC’s internal circuitry can be shutdown via the CE pin
signal.
<CL Auto-Discharge Function>
XC6503D can quickly discharge the electric charge at the output capacitor (C
a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the V
BLOCK DIAGRAM). The CL discharge resistance is set to 430Ω when VIN is 6.0V (TYP.) and V
discharge time of the output capacitor (C
) is set by the CL auto-discharge resistance (R
L
setting time constant of a CL auto-discharge resistance value (R
output voltage after discharge via the N-channel transistor is calculated by the following formula.
V = V
( V : Output voltage after discharge, V
auto-discharge resistance R
τ: C
L
OUT(E)
DCHG×CL
<Current Limiter, Short-Circuit Protection>
The protection circuit operates as a combination of an output current limiter and fold-back short circuit protection. When load
current reaches the current limit level, the output voltage drops. As a result, the load current starts to reduce with showing
fold-back curve. The output current finally falls at the level of 120mA when the V
<Thermal Shutdown>
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 voltage.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6503D series. In shutdown mode, output
at the V
pin will be pulled down to the V
OUT
XC6503P does not have the CE pin.
The XC6503D has a pulled down resistor at the CE pin in order to avoid an unstable operation with the CE pin open (the CE
pin is left open, operation will be stopped). However, the CE pin input current will increase slightly through the pulled down
resistor when operating. If the correct output voltage is applied to the CE pin, the logic is fixed and the IC will operate normally.
However, if the medium voltage is input, supply current may increase as a result of an internal through current.

■ 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. The XC6503 series operates even if without attaching an output capacitor. However, when wiring impedance is high,
operations may become unstable due to noise and/or phase lag depending on output current. Please wire the input
capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
3. The XC6503 installs fold-back current limit circuits. When start-up, this fold-back load curve affects its start-up
characteristics. The XC6503 having output current under 2.4V may not happen to start-up with the load conditions below.
In these cases, sequence control should be taken for connecting a load after the start-up execution.
