XC6213B122NL

XC6213 Series ETR0308_004 High Speed LDO Regulators, Low ESR Cap. Compatible, Ultra Small Package ■GENERAL DESCRIPTION The XC6213 series is a highly precise positive voltage LDO regulator with low noise manufactured using CMOS process. The series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 50mV increments within a range of 1.2V to 5.0V. The series is also compatible with low ESR ceramic capacitors, which give output stability. The current limiter's foldback circuit also operates as a short circuit protection for the output pin. The CE function enables the output to be turned off, resulting in greatly reduced power consumption. Ultra small package SSOT-24, SOT-25, and USP-4 are available. ■APPLICATIONS ●Mobile phones ●Cordless phones, Wireless communication equipment ●Portable games ●Cameras, Video recorders ●Portable AV equipment ●PDAs ■FEATURES Maximum Output Current Dropout Voltage Input Voltage Range Output Voltage Range Highly Accurate Low Power Consumption Stand-by Current : 150mA @ VOUT=3.0V, VIN=4.0V : 400mV @ IOUT = 100mA : 2.0 ~ 6.0V : 1.2 ~ 5.0V (50mV Increments) : ±2% : 35μA (TYP.) : Less than 0.1μA High Ripple Rejection : 60dB @ 10kHz Operating Temperature Range : - 40℃ ~ 85℃ Low ESR Capacitor Compatible : Ceramic capacitor Ultra Small Packages : SSOT-24 SOT-25 USP-4 ■TYPICAL APPLICATION CIRCUIT ●SSOT-24 package ■TYPICAL PERFORMANCE CHARACTERI STICS ●Ripple Rejection Rate vs. Ripple Frequency X C6213B302 VIN VOUT 90 Ripple Rejection Rate : RR (dB) VIN=VCE=4.0VDC+0.5p-pAC IOUT=50mA , CL=1.0μF(ceramic) CE CIN 1 μF VSS CL 1 μF 80 70 60 50 40 30 20 10 0 0.01 0.1 1 10 100 Ripple Frequency : f (KHz) 1/28 XC6213 Series ■PIN CONFIGURATION VOUT 5 NC 4 VIN 4 VOUT 3 V SS 2 V OUT 1 3 CE 4 V IN 1 VIN 2 VSS 3 CE 1 CE 2 VSS *The dissipation pad for the USP-4 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. 2) pin SOT-25 (SOT-23-5) (TOP VIEW) SSOT-24 (TOP VIEW) USP-4 (BOTTOM VIEW) ■PIN ASSIGNMENT PIN NUMBER SOT-25 3 2 5 1 4 SSOT-24 1 2 3 4 USP-4 3 2 1 4 PIN NAME CE VSS VOUT VIN NC FUNCTION On / Off Switch Ground Output Power Supply No Connection ■PRODUCT CLASSIFICATION ●Ordering Information XC6213①②③④⑤⑥ MARK ① ②③ ④ DESCRIPTION Type of Regulator Output Voltage Output Voltage Accuracy Packages SYMBOL B 12~50 2 A M ⑤ N G ⑥ Device Orientation R L : Output Voltage: ex.) 3.0V→ ② =3, ③= 0 : 100mV increments, ±2% accuracy ex.) 2.80V → ②=2, ③= 8, ④= 2 : 50mV increments, ±2% accuracy ex.) 2.85V → ②=2, ③= 8, ④= A : SOT-25 (SOT-23-5) : SSOT-24 : USP-4 : Embossed tape, standard feed : Embossed tape, reverse feed DESCRIPTION : High Active with no pull-down resistor (standard) 2/28 XC6213 Series ■BLOCK DIAGRAM VIN CE ON/OFF Control each circuit Current Limit VOUT R2 R1 Voltage Reference VSS *Diode inside the circuit is a protection diode. ■ABSOLUTE MAXIMUM RATINGS PARAMETER Input Voltage Output Current Output Voltage CE Input Voltage SOT-25 Power Dissipation SSOT-24 USP-4 Operating Temperature Range Storage Temperature Range * IOUT=Pd/(VIN-VOUT) SYMBOL VIN IOUT VOUT VCE Pd Topr Tstg RATINGS VSS – 0.3 ~ 7.0 500* VSS – 0.3 ~ VIN + 0.3 VSS – 0.3 ~ 7.0 250 150 120 - 40 ~ + 85 - 55 ~ + 125 Ta = 25℃ UNITS V mA V V mW ℃ ℃ 3/28 XC6213 Series ■ELECTRICAL CHARACTERISTICS ●XC6213B series PARAMETER Output Voltage SYMBOL VOUT(E) CONDITIONS IOUT=30mA, CE=VIN VIN=VOUT(T)+1.0V, VOUT(T)=1.20~1.45V, CE=VIN VIN=VOUT(T)+1.0V, VOUT(T)=1.50~2.95V, CE=VIN VIN=VOUT(T)+1.0V, VOUT(T)=3.00~4.05V, CE=VIN VIN=VOUT(T)+1.0V, VOUT(T)=4.10~5.00V, CE=VIN VIN=VOUT(T)+1.0V, 1mA≦IOUT≦100mA, CE=VIN IOUT = 30mA, CE=VIN IOUT=100mA, CE=VIN VIN=VOUT(T)+1.0V, CE=VIN VIN=VOUT(T)+1.0V∼6.0V, CE=VSS VOUT(T)+1.0V≦VIN≦6V IOUT=30mA, CE=VIN IOUT=30mA, CE=VIN - 40℃≦Topr≦85℃ VIN=[VOUT(T)+1.0 V] +0.5Vp-pAC IOUT=50mA, f=10kHz, CE=VIN VIN=VOUT(T) + 1.0V, CE=VIN VCE = VIN=VOUT(T) + 1.0V VIN=VOUT(T) +1.0V, VCE =VSS 25 2.0 1.3 - 0.1 - 0.1 MIN.
