Terminal protection for short circuit to +B when VCC terminal is open and for short circuit to GND when GND terminal is open. We recommend Schottky barrier diodes. IF ≥ 1 A — Be careful of the maximum rating. The ability to protect terminal lower. And there is some possibility of destruction. RFREG1 RFREG2 Output voltage = (1 + RFREG1/RFREG2) × 1.26 V 100 to 10 k Ω Unstable Loss of current increases GFREG3 Resistance for limiting base current of PNP transistor Choose resistance by a required output current value and hFE of PNP transistor Choose resistance by a required output current value and hFE of PNP transistor QFREG Output PNP transistor for FREG (We recommend Renesas 2SB857.) hFE = 50 to 200 Unstable Lower output current capability Notes: 1. We recommend Polyester film capacitor. To improve stability, take notes of the below precautions. (1) Use capacitor that is temperature independent. (2) Use capacitor that is bias voltage independent. (3) In order to bypass high frequency noise efficiently, mount the capacitor as close as possible to the VCC and GND of IC to eliminate PCB pattern inductance. 2. For using of the lower limit of recommended value, take notes of the below precautions. (1) Use capacitor that is temperature independent. (2) Use capacitor that is bias voltage independent. (3) To eliminate PCB pattern inductance mount the capacitor as close as possible to the output pin and GND of IC. 3. To improve stability, take notes of the below precautions. (1) Use capacitor that is temperature independent. (2) Use capacitor that is bias voltage independent. (3) ESR needs to be less than 10 Ω in all the temperature ranges to be used. (4) To eliminate PCB pattern inductance mount the capacitor as close as possible to the output pin and GND of IC. |
