'2002.1.25 Boost type Voltage Regulator with Reset R1151N SERIES 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 (Minimold) 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. Rev. 1.11 -5- 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 line 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 =2.31xC/(300x10-9 ) C: Capacitance value (F) Recommended pull-up resistance (R1) value is 470k. If the value is too small, released voltage may be shift, therefore, use 10k or more value resistor.
