Flywheel diode (Sanken AK04 recommended) qUse a Schottky barrier diode for D1, D2 and D3 and make sure that the reverse voltage applied to SW output terminal does not exceed the value (-1V) given in the maximum ratings. qIf you use a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may damage the IC. 117 qSLA3001M/3002M/3004M sTypical Characteristics (Ta=25C) SLA3001M (Regulator 2, VO=5V) Rise Characteristics 7.0 6.0 Line Regulation 5.10 IO=0A Load Regulation 5.10 VIN=15V =8V 5.05 5.05 Output Voltage VO (V) Output Voltage VO (V) Output Voltage VO (V) 5.0 IO =0 5.00 IO=1.0A 0.5A VIN=6V 5.00 1. 5A 4.0 3.0 A 4.95 4.95 0.5A 2.0 1.0 0 0 1.0A 4.90 4.90 4.85 4.80 0 4.85 4.80 0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 6 8 10 12 14 16 18 20 0.5 1.0 1.5 Input Voltage VIN (V) Input Voltage VIN (V) Output Current IO (A) Overcurrent Protection Characteristics 6.0 ON/OFF Control Characteristics 6 VIN=8V IO =1A VO=5V Thermal Protection Characteristics 6 VIN=8V IO=10mA 5 VO=5V 5.0 IO=30V 6V 5 8V Output Voltage VO (V) Output Voltage VO (V) Output Voltage VO (V) 3.0 4.0 15V 4.0 4 4 3.0 3 OFF 3 2.0 2 ON 1 2 1.0 1 0 0 1.0 2.0 3.0 4.0 0 0 1.0 2.0 0 20 60 100 140 180 Output Current IO (A) Output ON/OFF Control Voltage VC (V) Case Temperature Tc (C) Note on Thermal Protection: The thermal protection circuit is intended for protection against heat during instantaneous shortcircuiting.
