XC6503 Series ETR03046-009b 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 CL capacitor-less is possible because phase compensation is carried out internally unlike other LDOs where it is done 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 XC6503A/B/C/D has a chip enable function, which enables the entire circuit to be turned off by a low level input signal to the CE pin. When a CL capacitor is used, the IC can discharge the electric charge stored at the output capacitor through the internal switch while in standby state, and as a result the VOUT quickly returns to the VSS level. ■FEATURES ■APPLICATIONS ●Smart phones / Mobile phones ●Portable game consoles ●Modules (wireless, camera, etc.) ●Bluetooth modules ●Digital TV tuner modules Maximum Output Current : 500mA Input Voltage Range : 1.7V ~ 6.0V Output Voltage Range : 1.2V ~ 5.0V (0.05V increments) Output Accuracy : ±1.0% (2.0V ~ 5.0V) Temperature Stability : ±30ppm/℃ Dropout Voltage : 190mV@VOUT=2.8V, IOUT =300mA Low Power Consumption : 15μA (TYP.), 0.1μA (in standby) High PSRR : 55dB@1kHz, VOUT=2.8V Protection Current : Current Limiter (630mA TYP.) ±20mV (1.2V ~ 1.95V) Short-circuit Protection Thermal Shutdown CL Capacitor-Less : Internal Phase Compensation Operating Ambient Temperature : -40℃ ~ 85℃ Packages : USP-4, SOT-25, SOT-89-5 (XC6503A-D) Environmentally Friendly : SOT-89 (XC6503P) EU RoHS Compliant, Pb Free ■TYPICAL PERFORMANCE CHARACTERISTICS ■TYPICAL APPLICATION CIRCUIT X C6 5 0 3 x2 8 1 xx 5 CIN:0.1μF(ceramic) VSS CE VOUT 300 CL:0.1μF(ceramic) 2 250 3 4 NC SOT-25 (TOP VIEW) CE 3 2 VIN 4 1 VSS VOUT VIN=3.8V, tr=tf=5μs, IOUT=10⇔150mA, Ta=25℃          CL =0.1μF(ceramic)          without CL 3.4 3.1 OutputVoltage 200 2.8 2.5 150 OutputCurrent 100 2.2 50 1.9 0 1.6 OutputVoltage : VOUT (V) 1 OutputCurrent : I OUT (mA) VIN CL:0.1μF(ceramic) CIN:0.1μF(ceramic) USP-4 (TOP VIEW) Time : 40μs/div 1/22 XC6503 Series ■BLOCK DIAGRAMS XC6503 A Series XC6503 B Series VOUT VIN VOUT VIN CFB Current Limit & TSD R1 + Error Amp - CE ON/OFF Control CFB Current Limit & TSD each circuit RDCHG + Error Amp - R2 Voltage Reference CE ON/OFF Control each circuit R1 R2 Voltage Reference /CE VSS VSS XC6503 C Series XC6503 D Series VIN VOUT VIN VOUT CFB Current Limit & TSD R1 + Error Amp - CE ON/OFF Control CFB Current Limit & TSD + Error Amp - R2 CE Voltage Reference VSS each circuit ON/OFF Control Voltage Reference each circuit XC6503 P Series VIN VOUT CFB Current Limit & TSD R1 + Error Amp - R2 Voltage Reference VSS * Diodes inside the circuits are ESD protection diodes and parasitic diodes. 2/22 R1 RDCHG R2 /CE VSS XC6503 Series ■PRODUCT CLASSIFICATION 1) Ordering Information XC6503①②③④⑤⑥-⑦(*1) DESIGNATOR ITEM SYMBOL DESCRIPTION A B ① C Type of Regulator Selection Guide D P ②③ Output Voltage 12~50 ex.) ②=2, ③=8 → 2.8V 0.1V increments 1 ④ ±0.02V (1.2~1.9V), ±1% (2.0~5.0V) ex.) 1.80V → ②=1, ③=8、④=1 Output Accuracy 0.05V increments A ±0.02V(1.25~1.95V), ±1%(2.05~4.95V) ex.) 1.85V → ②=1, ③=8、④=A ⑤⑥-⑦(*1) Packages (Order Unit) GR-G USP-4 (3,000pcs/Reel) *A/B/C/D Type MR-G SOT-25 (3,000pcs/Reel) *A/B/C/D Type PR-G (*1) SOT-89 (1,000pcs/Reel) * P Type SOT-89-5 (1,000pcs/Reel) *A/B/C/D Type The “-G” suffix denotes Halogen and Antimony free as well as being fully EU RoHS compliant. 2) Selection Guide TYPE CURRENT LIMITTER SHORT PROTECTION THERMAL SHUTDOWN PROTECTION CE Pull-down RESISTOR CL DISCHARGE CE PIN A B C D P Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes No No Yes Yes No No Yes No Yes No Yes Yes Yes Yes No 3/22 XC6503 Series ■PIN CONFIGURATION VOUT V IN 2 5 4 VSS 2 VOUT 5 VSS 2 3 CE VOUT 1 4 VIN 1 VIN USP-4 NC 4 2 VSS 3 CE 1 2 3 NC VSS CE SOT-25 (BOTTOM VIEW) (TOP VIEW) 1 2 3 VOUT VSS VIN SOT-89-5 SOT-89 (TOP VIEW) (TOP VIEW) *The dissipation pad for the USP-4 package should be solder-plated in reference mount pattern and metal masking so as to enhance mounting strength and heat release.

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 circuit protection operate 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. VOUT VIN CFB Current Limit & TSD + Error Amp - CE ON/OFF Control Voltage Reference R1 RDCHG R2 /CE each circuit XC6503 Series D Type VSS XC6503D Series XC6503 B/D can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the CE pin, which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL discharge resistance is set to 430Ω when VIN is 6.0V (TYP.) and VOUT is 5.0V (TYP.). Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (RDCHG) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value (RDCHG) 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 formula. V = VOUT x e –t/τ, or t=τln (VOUT(E) / V) ( V : Output voltage after discharge, VOUT(E) : Initial Output voltage, t: Discharge time, τ: CL auto-discharge resistance RDCHG×CL Output capacitance 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 foldback curve. The output current finally falls at the level of 120mA when the VOUT pin is short-circuited. 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. The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6503 A/B/C/D series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1, R2 and CL auto-discharge resistance RDCHG. Please note the XC6503P does not have the CE pin. The XC6503 C/D 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. 10/22 XC6503 Series ■ 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 and Load Resistance (RLOAD) ≧ 4.8Ω 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.
