ETR0356-002a
Low Power Consumption, High Speed 200mA LDO Regulator - 10.5V Input
■GENERAL DESCRIPTION
Even the XC6505 series is a low power consumption such as 5.5μA, the IC is a high speed CMOS LDO regulator that
features high accurate, low noise, high ripple rejection, and low dropout. The series consists of a voltage reference, an error
amplifier, a driver transistor, a current limiter, a phase compensation circuit and a thermal shutdown circuit.
The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series
enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin
quickly returns to the VSS level.
The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate
when the output current reaches current limit level or the junction temperature reaches temperature detection level.

■PIN CONFIGURATION
*The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking so as to
enhance mounting strength and heat release.
If the pad needs to be connected to other pins, it should be connected to the VSS (No. 5) pin.

XC6505 Series
■OPERATIONAL EXPLANATION
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET which is connected to the VOUT pin is then driven by the subsequent output signal. The output voltage at
the VOUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protection circuit
operate in relation to the level of output current and heat dissipation. Further, the IC’s internal circuitry can be shutdown via the
CE pin signal.
<CE Pin>
The XC6505 Series is able to shut down the regular circuit using the CE pin signal. In the shutdown state, the VOUT pin is
pulled down by R1 and R2 to the VSS level. In the XC6505B Series, the CL discharge resistance is connected in parallel with R1
and R2 when power is supplied to VIN, shortening the time until the VSS level is reached. Operation is unstable when the CE pin
is open, and thus the VIN voltage or the VSS voltage should be input into the CE pin. Although the logic is fixed and operation is
normal as long the voltage satisfies the CE pin voltage specification, inputting an intermediate voltage may cause the supply
current to increase due to the flowthrough current in the IC internal circuit.
<CL Auto-Discharge Function>
The XC6505B type is capable of high-speed discharge of the charge that collects on the output capacitor (CL below). This is
accomplished by the N-channel MOSFET connected between the VOUT and VSS pins in the block diagram, and takes place
when the L-level signal (IC internal circuit shutdown signal) of the CE pin is input. The CL discharge resistance is set to 400 Ω
(when VIN = 10.5 V, VOUT = 5.0 V typical). The CL discharge time is determined by this CL discharge resistance and CL. Letting
the time constant of the CL discharge resistance RDCHG and CL be τ (τ = C × R), the output voltage after discharge by the
N-channel MOSFET can be obtained from the CR discharge equation below.
V= VOUT(E) ×e-t/
or ｔ=τ×ln（VOUT(E)/V）
τ
V：Output voltage after discharge
VOUT(E)：Output voltage
t：Discharge time
τ：CL auto-discharge resistance RDCHG × CL Output capacitor value CL
<Current Limiter, Short-Circuit Protection>
The XC6505 series’ fold-back circuit operates as an output current limiter and a short protection circuit for 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 short-circuited to the VSS pin, the current falls and reaches about 110mA.
<Thermal Shutdown>
The XC6505 Series has an internal thermal shutdown (TSD) circuit for protection against overheating.
When the junction temperature reaches the detection temperature, the driver transistor is forcibly turned off. When the junction
temperature falls to the release temperature with the driver transistor still in the off state, the driver transistor turns on (automatic
recovery) and restarts regulator operation.

Series
■OPERATIONAL EXPLANATION
＜Input/output capacitor＞
The XC6505 Series uses an output capacitor (CL) for phase compensation. For this reason, if a small capacitor or low
withstand-voltage capacitor is used for CL, DC bias dependence causes a smaller capacitance value, and phase shifting that
results in unstable operation may occur. Exercise caution when selecting the capacitor. Recommended capacitances for the
XC6505 Series are shown below.
For the input capacitor (CIN), select a capacitance of 1.0 µF or higher to stabilize the input power.

■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 wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
3. If the input voltage fluctuates by 1.5 V or more and is at a slope of 0.1 V/µs or more, output voltage undershoot may
become more pronounced. In this case, use a larger input capacitor (CIN) or otherwise adjust so that the through rate is
less than 0.1 V/µs.
4. If a small capacitor is used for the output capacitor (CL below), capacitance loss due to DC bias dependence will
become more pronounced. This will increase the tendency for phase shifting to occur, resulting in unstable operation.
Test thoroughly before using.
For guidelines for the CL capacitance, check the XC6505 recommended capacitance characteristics (refer to
Operational Explanation, Input/Output Capacitors).
5. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
