XC6228D122VR-G

XC6228 Series ETR0360-002 300mA High Speed LDO Regulator with ON/OFF Switch ■GENERAL DESCRIPTION The XC6228 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation 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 output stabilization capacitor CL is also compatible with low ESR ceramic capacitors. The output voltage is selectable from 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.1V, 3.3V which fixed by laser trimming technologies. The over current protection circuit is built-in. This protection circuit will operate when the output current reaches current limit level. ■APPLICATIONS ■FEATURES ●Mobile devices Maximum Output Current Input Voltage Range Output Voltages ●Mobile phones ■TYPICAL APPLICATION CIRCUIT Low ESR Capacitors CE Function Small Package Environmentally Friendly : EU RoHS Compliant, Pb Free Dropout Voltage Low Power Consumption Stand-by Current High Ripple Rejection Protection Circuits ■ TYPICAL PERFORMANCE CHARACTERISTICS ●Load Transient Response XC6228D25 tr = tf = 0.5μs, Ta = 25℃, IOUT = 1⇔150mA VIN = 3.5V, CIN = 1μF (ceramic), CL = 1μF (ceramic) 2.60 400 2.55 350 2.50 2.45 Output Voltage 2.40 250 200 2.35 2.30 300 150 Output Current 2.25 100 50 2.20 Output Current Iout[mA] ●Modules Output Voltage: VOUT [V] ●Wireless communications : 300mA : 1.6～5.5V : 1.2V, 1.5V, 1.8V, 2.5V，2.8V，3.0V，3.1V，3.3V （±2%） : 200mV＠IOUT=300mA (VOUT=3.0V) : 100μA : 0.1μA : 80dB＠f=1kHz : Current Limit （400mA） Short Circuit Protection : CIN=1μF, CL=1μF : Active High, CL High Speed Discharge : SOT-25J 0 Time [20μs/div] 1/21 XC6228 Series ■BLOCK DIAGRAMS * Diodes inside the circuits are ESD protection diodes and parasitic diodes. ■PRODUCT CLASSIFICATION ●Ordering Information XC6228①②③④⑤⑥-⑦ DESIGNATOR ① ④ (*1) ITEM SYMBOL Regulator Type D CE Active High, CE pin Pull-down resistor, CL discharge 12 1.2V 15 1.5V 18 1.8V 25 2.5V 28 2.8V 30 3.0V 31 3.1V 33 3.3V Output Voltage ②③ ⑤⑥-⑦ (*1) (*1) Output Voltage Accuracy 2 Package VR-G DESCRIPTION ±2% SOT-25J (3,000/Reel) The “-G” suffix indicates that the products are Halogen and Antimony free as well as being fully RoHS compliant. 2/21 XC6228 Series ■PIN CONFIGURATION ■PIN ASSIGNMENT PIN NUMBER PIN NAME FUNCTIONS 1 5 2 3 4 VIN VOUT VSS CE NC Power Input Output Ground ON/OFF Control No Connection ■PIN FUNCTION ASSIGNMENT CE INPUT SIGNAL IC OPERATION STATE H ON L OFF (Stand-by) OPEN OFF (Stand-by) * * An internal pull-down resister maintains the CE pin voltage to be low. 3/21 XC6228 Series ■ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNITS Input Voltage Output Current Output Voltage CE Input Voltage VIN IOUT VOUT VCE VSS-0.3～VSS+7.0 500 (*1) VSS-0.3～VIN+0.3 VSS-0.3～VSS+7.0 200 500 (PCB mounted) (*2) -40～+85 -55～+125 V mA V V Power Dissipation SOT-25J Operating Temperature Range Storage Temperature Range (*1) IOUT≦Pd / (VIN-VOUT) (*2) This is a reference data taken by using the test board. 4/21 Pd Topr Tstg mW ℃ ℃ XC6228 Series ■ELECTRICAL CHARACTERISTICS Ta=25℃ ●XC6228D Series PARAMETER Output Voltage SYMBOL VOUT(E) (*1) CONDITIONS VCE=VIN, IOUT=10mA MIN.

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. Further, the IC’s internal circuitry can be shutdown via the CE pin signal. The XC6228 series needs an output capacitor CL for phase compensation. and the ground pin (VSS) as close as possible. Please place an output capacitor (CL) at the output pin (VOUT) Please use the output capacitor (CL) is 1.0μF or larger. For a stable power input, please connect an input capacitor (CIN) of 1.0μF between the VIN pin and the VSS pin. The XC6228 has current limiter and droop shape of fold-back circuit. limiter circuit operates and the output voltage drops. goes to decrease. When the load current reaches the current limit, the droop current When the output voltage dropped, the fold-back circuit operates and the output current The output current finally falls at the level of 50mA when the output pin is short-circuited. The IC's internal circuitry can be shutdown via the signal from the CE pin. In shutdown mode, the XC6228 series enables the electric charge at the output capacitor (CL) to be discharged via the internal switch located between the VOUT and VSS pins, and as a result the VOUT pin quickly returns to the VSS level. The XC6228 series has a pull-down resistor at the CE pin inside, so that the CE pin input current flows. ■ 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 the noise and/or phase lag depending on output current. Please strengthen VIN and VSS wiring in particular. 3． The input capacitor CIN and the output capacitor CL should be placed to the as close as possible with a shorter wiring. 4． 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. 7/21 XC6228 Series ■TEST CIRCUITS ●Circuit ① ●Circuit ② ●Circuit ③ ●Circuit ④ 8/21
