Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to Product specification ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (Refer to test circuit, Io = -500mA, Vi = -14V, Ci= 2.2uF, Co=1.0uF unless otherwise specified) ( Ta = 25 C) O ( Ta = 25 C) O TO-220 TIGER ELECTRONIC CO.,LTD |
