XC6505 Series
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.
enables the electric charge at the output capacitor C
quickly returns to the V
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 V

■ 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 V the V
pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protection circuit
OUT
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 regulator circuit using the CE pin signal. In the shutdown state, the V pulled down by R1 and R2 to the V and R2 when power is supplied to V is open, and thus the V
voltage or the VSS voltage should be input into the CE pin. Although the logic is fixed and operation is

The XC6505B type is capable of high-speed discharge of the charge that collects on the output capacitor (C accomplished by the N-channel MOSFET connected between the V when the L-level signal (IC internal circuit shutdown signal) of the CE pin is input. The C (when V

<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 V
pin, the current falls and reaches about 110mA.
SS
<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.

■ 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 C 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 (C
), 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 (C
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 (C less than 0.1 V/µs.
4. If a small capacitor is used for the output capacitor (C 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 C
capacitance, check the XC6505 recommended capacitance characteristics (refer to

Operational Explanation, Input/Output Capacitors).
