Flywheel diode (Sanken AK04 recommended) ●Use 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. ●If 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 ●SLA3001M/3002M/3004M ■Typical Characteristics (Ta=25°C) SLA3001M (Regulator 2, VO=5V) Line Regulation 6.0 5.05 A 5.0 4.0 5A 1. 3.0 0.5A 1.0A 2.0 IO=0A 5.00 1.0 2.0 3.0 4.0 5.0 6.0 4.95 4.90 4.80 0 7.0 6 5.0 5 6 8 10 12 14 18 20 4.80 0 3.0 2.0 1.0 1.0 2.0 3.0 VO=5V 5 3 OFF 2 ON 0 0 4.0 1.5 VIN=8V IO=10mA VO=5V 4 Output Current IO (A) 1.0 Thermal Protection Characteristics 4 3 2 1 0 0 0.5 Output Current IO (A) Output Voltage VO (V) 15V Output Voltage VO (V) 6V 16 6 VIN=8V IO =1A 8V 4.90 ON/OFF Control Characteristics 6.0 IO=30V 4.95 Input Voltage VIN (V) Overcurrent Protection Characteristics Output Voltage VO (V) VIN=6V 5.00 4.85 Input Voltage VIN (V) 4.0 VIN=15V =8V 5.05 IO=1.0A 0.5A 4.85 1.0 0 0 Load Regulation 5.10 Output Voltage VO (V) 5.10 Output Voltage VO (V) 7.0 IO =0 Output Voltage VO (V) Rise Characteristics 1 1.0 2.0 3.0 0 20 4.0 60 Output ON/OFF Control Voltage VC (V) 100 140 180 Case Temperature Tc (°C) Note on Thermal Protection: The thermal protection circuit is intended for protection against heat during instantaneous shortcircuiting.
