| Boost type Voltage Regulator with Reset R1151N SERIES NO. EA-092-0307 OUTLINE The R1151N Series are CMOS-based boost type voltage regulator ICs with high output voltage accuracy, low supply current, and high ripple rejection. Each of these voltage regulator controllers consists of a voltage reference unit, an error amplifier, comparators, resistors for output and reset voltage setting, a current limit protection circuit, and a chip enable circuit. In addition to low consumption current by CMOS process, the chip enable function prolongs the battery life. Dynamic response and ripple rejection of the R1151N Series are excellent, further these are low noise type, plus maximum operating input voltage tolerance is up to 18.5V thus these ICs are very suitable for the power supply for hand, held equipment and other power management applications using AC adapter input voltage. The output voltage of these ICs is internally fixed with high accuracy. Since the package for these ICs is SOT-23-6 (Mini-mold) package, high density mounting of the ICs on boards is possible.

The base current is monitored with the base current limit circuit. If the base current may be too large, the protection circuit works, further, output voltage is monitored with the built-in voltage detector. If the set detector threshold voltage is detected, reset signal will be output. TECHNICAL NOTES When using these ICs, consider the following points: In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, be sure to use as much as 10F capacitor as CL with good frequency characteristics and ESR (Equivalent Series Resistance). The best suitable equivalent series resistor value (ESR) is approximately 1. If the ESR of the output capacitor is too large, output may be unstable, therefore fully evaluation is necessary. Make VDD and GND lines sufficient. When their impedance of these is high, noise pickup or unstable operation may be the result. Connect a capacitor with a capacitance value of as much as 10F between VDD and GND as close as possible to these pins. Set external components, especially output capacitor, as close as possible to the ICs. Refer to the next equation to calculate the output delay time of C version and decide the capacitance value for the delay time. tPLH =1.83xC/(300x10-9) C: Capacitance value (F) Recommended pull-up resistance (R1) value is 470k. If the value is too small, released voltage may shift, therefore, use 10k or more value resistor. 6 R1151N TEST CIRCUITS PNP 1 VIN 6 R1 2 VDET 5 R1151NxxC 4 C1 C2 2 5 3 IOUT VIN 6 R1151NxxC 4 C1 C2 3 1 IOUT PNP Fig.1 Standard test Circuit R1=470k C1=220pF, C2=10F Fig.2 Supply Current Test Circuit C1=220pF, C2=10F PNP 1 VIN 6 R1151NxxC P .G. 2 5 4 C1 C2 P .G. 2 5 3 IOUT VIN 6 1 PNP IOUT 3 R1151NxxC 4 C1 C2 Fig.3 Ripple Rejection, Line Transient Response Test Circuit Fig.4 Load Transient Response Test Circuit C1=220pF, C2=10F C1=220pF, C2=10F TYPICAL APPLICATION IN + CI VDD EXT VOUT PNP Tr OUT + CL R1 VDET GND RESET CD R1151NxxxC + CD (External Components) C1 10F R1=470k PNP Tr.: 2SA1441, 2SB940, 2SB703 CL 10F 7 R1151N TYPICAL CHARACTERISTICS 1) a.

externally made for securing stable operation even if the load current is varied. For this purpose, be sure to use a capacitor for the output pin with good frequency characteristics and ESR (Equivalent Series Resistance) of which is in the range described as follows: VDET CD EXT VIN Ceramic Capacitor 4.7F R1151NxxxxC VOUT GND Ceramic Capacitance 10F ESR IOUT Spectrum Analyser S.A. VIN Measuring Circuit for white noise; R1151NxxxC The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions when the white noise level is under 40V (Avg.) are marked as the hatched area in the graph. 25 R1151N VR=2.5V (2SA1441) Equivalent Series Resistance ESR () Equivalent Series Resistance ESR () 100 100 VR=9.0V (2SA1441) 10 10 1 1 0.1 0.1 0.01 0 50 100 150 200 250 300 350 400 450 500 0.01 0 50 100 150 200 250 300 350 400 450 500 Output Current IOUT(mA) Output Current IOUT(mA) VR=2.5V (2SB703) Equivalent Series Resistance ESR () Equivalent Series Resistance ESR () 100 100 VR=9.0V (2SB703) 10 10 1 1 0.1 0.1 0.01 0 50 100 150 200 250 300 350 400 450 500 0.01 0 50 100 150 200 250 300 350 400 450 500 Output Current IOUT(mA) Output Current IOUT(mA) VR=2.5V (2SB940) Equivalent Series Resistance ESR () Equivalent Series Resistance ESR () 100 100 VR=9.0V (2SB940) 10 10 1 1 0.1 0.1 0.01 0 50 100 150 200 250 300 350 400 450 500 0.01 0 50 100 150 200 250 300 350 400 450 500 Output Current IOUT(mA) Output Current IOUT(mA) 26 |
