XC6216/XE6216 Series ETR03021-027 28V Low Power Consumption 150mA Voltage Regulators (with Stand-by Function) ■GENERAL DESCRIPTION XC6216/XE6216 series are positive voltage regulator ICs with 28V of operation voltage. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit plus a driver transistor. The output voltage is selectable in 0.1V increments within the range of 1.8V to 12V using laser trimming technologies. With external resistors, the output voltage range can be expanded from 2.0V to 23V. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. 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 limit level. The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption. ■FEATURES ■APPLICATIONS ●Car audio, Car navigation systems ●Note PCs / Tablet PCs ●Mobile devices / terminals ●Digital still cameras / Camcorders ●Smart phones / Mobile phones ●Multi-function power supplies ■ TYPICAL APPLICATION CIRCUIT Max Output Current : More than 150mA (200mA limit) (VIN=VOUT+3.0V) Dropout Voltage : 300mV@IOUT=20mA Input Voltage Range : 2.0V~28.0V Output Voltage Range : 1.8V~12.0V (0.1V increments) 2.0V~23V with external resistors Fixed Output Accuracy :±2% ±1% (Vout≧2.00V) ±20mV (Vout≦1.9V) Low Power Consumption : 5μA Stand-by Current : Less than 0.1μA High Ripple Rejection : 30dB@1kHz Operating Temperature : -40℃~+85℃ Low ESR Capacitor : Ceramic Capacitor Compatible Built–in Protection : Current Limit Circuit Thermal Shutdown Circuit Operating Ambient Temperature : -40℃ ~ 85℃ Packages : SOT-25, SOT-89, SOT-89-5, USP-6C, SOT-223, TO-252 USP-6B06, SOT-23 Environmentally Friendly : EU RoHS Compliant, Pb Free ■ TYPICAL PERFORMANCE CHARACTERISTICS ●Output Voltage vs. Input Volatage Fixed Output Voltage XC6216B/XE6216B Series VIN VOUT R21 CIN 1uF CE VOFB VSS CL R22 1uF 100kΩ 設定電圧外部設定品 Output Voltage External Setting XC6216C/XE6216Cシリーズ XC6216C Series 1/38 XC6216/XE6216 Series ■ BLOCK DIAGRAMS ●XC6216 Series ●XC6216 B Type ●XC6216 C Type ●XC6216 D Type ●XE6216 Series ●XE6216 B Type *Diodes inside the circuit are an ESD protection diode and parasitic diodes. 2/38 XC6216/XE6216 Series ■PRODUCT CLASSIFICATION ●Ordering Information XC6216①②③④⑤⑥-⑦(*1) : CE function (Active High) Fixed output voltage 1.8V ~ 12.0V(0.1V increments) DESIGNATOR ITEM ① Type and Options of Regulators ②③ Output Voltage ④ Output Voltage Accuracy (*2) ⑤⑥-⑦(*1) Packages (Order Unit) SYMBOL B C 18 ~ C0 20 2 1 MR-G PR-G ER-G 8R-G DESCRIPTION Fixed output voltage Output voltage externally set (VOFB=2.0V) (*3) For the voltage within 1.8V ~ 9.9V (0.1V increments); e.g. 2.5V ⇒ 25, 5.0V ⇒ 50 For the voltage within 10.0V ~ 12.0V (0.1V increments); e.g. 10.6V ⇒ A6, 11.2V ⇒ B2, 12.0V ⇒ C0 For C type (output voltage externally set), VOFB=2.0V only ±2% VOUT≧2.00V：±1%,VOUT≦1.9V：±20mV (*3) SOT-25 (3,000pcs/Reel) SOT-89-5 (1,000pcs/Reel) USP-6C (3,000pcs/Reel) USP-6B06 (5,000pcs/Reel) The “-G” suffix denotes Halogen and Antimony free as well as being fully EU RoHS compliant.

The Pchannel MOSFET which is connected to the VOUT pin is then driven by the subsequent controlled signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protect 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’s signal. The XC6216/XE6216 series includes a current fold-back circuit as a short circuit protection. When the load current reaches the current limit level, the current fold-back circuit operates and output voltage drops. The output voltage drops further and output current decreases. When the output pin is shorted, a current of about 30mA flows. The IC’s internal circuitry can be shutdown via the signal from the CE pin with the XC6216/XE6216 series. In shutdown mode, output at the VOUT pin will be pulled down by R11 and R12 to the VSS level. Note that as the XC6216/XE6216 series has no pull down resistor so that it will become unstable with the CE pin open. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC’s internal circuitry if a medium voltage is applied. 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. For the stable operation of the IC, over 2.0V of input voltage is necessary. The output voltage may not be generated normally if the input voltage is less than 2.0V. ■ NOTES ON USE 1． Please use this IC within the stated absolute maximum ratings. 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. Phase compensation inside the IC is performed in the XC6216/XE6216 series. Therefore, an abnormal oscillation does not occur even if there is no output capacitor CL. An input capacitor CIN around 0.1μF~1.0μF between the power input pin (VIN) and the ground pin (VSS) is required for input stability. Also, the output voltage fluctuation such as under shoot or over shoot, which occurs because of the load change can be controlled by placing the output capacitor CL around 0.1μF~1.0 μF between the VOUT pin and VSS pin. The input capacitor (CIN) and the output capacitor (CL) should be placed to the IC as close as possible with a shorter wiring. 20/38 XC6216/XE6216 Series ■ NOTES ON USE 4. Notes on setting output voltage externally (C type) Ta=25℃ The output voltage can be set externally by the following equation: I21=IFB+I22 ……………………………………………………………………… I22=2.0V/R22 ……………………………………………………………………… I21=IFB+2.0V/R22 ……………………………………………………………………… If the equation (3) is assigned to the equation (2), the equation becomes as below: VOUT=2.0V+R21・I21 ……………………………………………………………………… For this, the following equation can be used for setting output voltage externally: VOUT=2.0V+R21・I21 ……………………………………………………………………… And the equation (4) will be; VOUT=2.0V+R21 ・(IFB+2.0V/R22) ……………………………………………………………………… =2.0V・(R21 + R22) / R22 + R21・IFB ……………………………………………………………………… The second term of the equation (6), R21・IFB, is the cause of the output accuracy error. The IFB can be calculated by the following equation: IFB=2.0V / RFB ……………………………………………………………………… The cause of the output accuracy error, R21・IFB can be calculated by the equation below; R21･IFB=R21・2.0V/ RFB =2.0V・R21 / RFB ……………………………………………………………………… Accordingly, if R21
