XB1086 Series ETR0325-008 1.5A Positive Voltage Regulator ■GENERAL DESCRIPTION The XB1086 is a series of low dropout positive voltage regulators with a high output current capability of 1.5A. Stable output can be maintained by using 10μF (CIN) and 22μF (CL) of tantalum capacitors. The XB1086P series is available in the fixed voltage types of 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V. The XB1086K is also available as a voltage adjustable type which can set the output voltage with only two external resistors. With an over current and thermal protection circuit built-in, the IC is disabled for protection when an output current reaches limit current or junction temperature increases up to limit temperature. The XB1086 series is available in TO-252 package. ■APPLICATIONS ■FEATURES ● High efficiency linear regulators Maximum Output Current Maximum Operating Voltage Output Voltage : More than 1.5A (within Pd) : 15V : 1.5V, 1.8V, 2.5V, 3.3V, 5.0V (XB1086P), Externally Set (XB1086K / Reference Voltage 1.25V (TYP.)) : ±1% ( Tj =25℃) Output Voltage Accuracy : 1.3V @ IOUT=1.5A (TYP.)

Please set it so that an electric current (IR1) flowing through R1 is as above 5mA. The output voltage is given by the following equation. 5/12 XB1086 Series ■TEST CIRCUITS 6/12 XB1086 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. 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 IC 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. 7/12 XB1086 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (1) Output Voltage vs. Output Current (2) Output Voltage vs. Input Voltage XB1086P331 XB1086P331 3.5 Output Voltage: VOUT(V) Output Voltage: VOUT(V) VIN=4.9V VIN=4.9V CIN=10μF (Tantalum), CL=22μF (Tantalum) CIN=10uF(Tantal）、CL=22uF(Tantal） 3.0 2.5 2.0 Ta=85℃ 1.5 Ta=25℃ Ta=0℃ 1.0 0.5 0.0 0 300 600 900 1200 Output Current: IOUT (mA) IOUT=10mA IOUT=10mA CIN=10μF (Tantalum), CL=22μF (Tantalum) CIN=10uF(Tantal）、CL=22uF(Tantal） 3.5 3.0 2.5 2.0 Ta=85℃ Ta=25℃ Ta=0℃ 1.5 1.0 0.5 0.0 1500 0 2 CIN=10μFCIN=10uF(Tantal）、CL=22uF（Tantal） (Tantalum), CL=22μF (Tantalum) Supply Current: ISS (mA) Dropout Voltage: Vdif （V) CIN=10μF (Tantalum), CL=22μF (Tantalum) CIN=10uF(Tantal）、CL=22uF(Tantal） 1.4 1.2 1.0 Ta=0℃ Ta=25℃ Ta=85℃ 0.4 0.2 0.0 0 300 600 900 1200 Output Current: IOUT (mA) 6 5 4 Ta=0℃ Ta=25℃ Ta=85℃ 3 2 1 0 0 1500 2 1.26 1.25 1.24 1.23 1.22 8/12 10 20 30 40 50 60 70 Ambient Temperature: Ta (℃) 8 10 XB1086K12B (VOUT=3.3V) VIN=4.9V VIN=4.9V CIN=10uF(Tantal）、CL=22uF(Tantal） CIN=10μF (Tantalum), CL=22μF (Tantalum) Adjust Pin Current: IADJ (μA） Reference Voltage: VREF （V) XB1086K12B （VOUT=3.3V) 0 4 6 Supply Voltage: Input Voltage: VINVIN(V) (V) (6) Adjust Pin Current vs. Ambient Temperature (5) Reference Voltage vs. Ambient Temperature 1.27 10 XB1086P331 XB1086P331 0.6 8 (4) Supply Current vs. Input Voltage (3) Dropout Voltage vs. Output Current 0.8 4 6 Supply Voltage: VIN(V) Input Voltage: VIN (V) 80 90 IOUT=10mA IOUT=10mA CIN=10μF (Tantalum), CL=22μF (Tantalum) CIN=10uF(Tantal）、CL=22uF(Tantal） 100 80 60 40 VIN=4.8V 20 0 0 10 20 30 40 50 60 70 Ambient Temperature: Ta (℃) 80 90 XB1086 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 1(7) Load Transient Response XB1086P331 XB1086K12B (VOUT=3.3V) VIN=4.8V VIN=4.8V CIN=CL=10μF (Tantalum) CIN=CL=10μF(Tantal) VOUT 1.6 3.4 1.2 3.2 0.75A 0.8 IOUT 0.4 3 2.8 0.1A 0.0 3.6 2.0 1.6 VOUT 3.4 3.2 1.2 0.8 0.4 IOUT 0.75A 3.0 0.1A 2.8 2.6 0.0 2.6 Time（10μs/DIV） OutputVoltage:VOUT(V) 3.6 Output Voltage: VOUT(V) Output Current: IOUT(A) 2.0 Output Current:IOUT(A) VIN=4.8V VIN=4.8V CIN=CL=10μF(Tantal) CIN=CL=10μF (Tantalum) Time（10μs/DIV） (8) Input Transient Response XB1086K12B (VOUT=3.3V) CIN=1μF (Tantalum), CL=10μF (Tantalum) CIN=1μF(Tantal),CL=10μF(Tantal) VOUT 10 3.30 8 3.28 3.26 7 6 3.32 Supply Voltage: VIN(V) 9 IOUT=100mA IOUT=100mA CIN=1μF (Tantalum), CL=10μF (Tantalum) CIN=1μF(Tantal),CL=10μF(Tantal) Output Voltage: (V) Output Voltage: VOUT VOUT(V) Supply Voltage: VIN(V) 10 IOUT=100mA IOUT=100mA VIN 5.8V 3.24 4.8V 5 3.22 4 3.20 3.35 VOUT 9 3.33 8 3.31 7 VIN 3.29 5.8V 6 3.27 4.8V 5 3.25 4 Time（20μs/DIV） 3.23 OutputVoltage: Voltage: VOUT(V) Output VOUT (V) XB1086P331 Time（20μs/DIV） (9) Ripple Rejection Rate 100 XB1086K12B (VOUT=3.3V) VIN=6.3VDC+1.0Vp-pAC VIN=6.3VDC+1.0Vp-pAC IOUT=1A, Ta-25℃, CL=25μF (Tantalum) IOUT=1ATa=25℃,CL=25μF(Tantal) 80 60 40 20 0 0.01 0.1 1 0.1 1 1010 ripple rejection rate（kHz) Ripple Frequency: f (kHz) 100 VIN=6.3VDC+1.0Vp-pAC VIN=6.3VDC+1.0Vp-pAC Ripple Rejection Rate: PSRR (dB) ripple rejection rate（ｄB) rippleRejection rejection rate（ｄB) Ripple Rate: PSRR (dB) XB1086P331 100 IOUT=1A, Ta-25℃, CL=25μF (Tantalum) IOUT=1A、Ta=25℃、CL=25μF(Tantal) 80 60 40 20 0 0.01 0.1 0.1 11 1010 ripple rejection rate（kHz) 100 Ripple Frequency: f (kHz) 9/12 XB1086 Series ■ PACKAGING INFORMATION ●TO-252 6.35-6.75 4.94-5.50 0.46-0.61 0.64-0.89 0.64-0.89 0.64-0.89 4.32 MIN (2.29) (2.29) BOTTOM VIEW UNIT: mm 10/12 XB1086 Series ■MARKING RULE ●TO-252 （mark header：①～⑥） *Mark header does not change with a lot. ①② represents product series MARK ① ② ③ ① ② ④ ⑤ ⑥ 8 6 ⑦ ⑧ ⑨ XB1086****J* ③ represent the type of regulator 2 1 PRODUCT SERIES MARK PRODUCT SERIES P XB1086P***J* K XB1086K***J* 3 TO-252 (TOP VIEW) ④⑤ represents output voltage MARK OUTPUT VOTLAGE PRODUCT SERIES ④ ⑤ 1 5 1.5V XB1086P151J* 1 8 1.8V XB1086P181J* 2 5 2.5V XB1086P251J* 3 3 3.3V XB1086P331J* 5 0 5.0V XB1086P501J* 1 2 ADJ XB1086K12BJ* ⑥ represents output voltage accuracy and output type OUTPUT VOLTAGE ACCURACY MARK (OUTPUT TYPE) PRODUCT SERIES 1 1% XB1086P**1J* B ADJ XB1086K12BJ* ⑦ represents the last digit of production year ex.)
