1 The LM293 is a dual positive.0 low dropout voltage regulator, designed for standby power systems. The main output is capable of supplying 70 ma for microprocessor power, and can be turned on and off by the switch/reset input. The other output is dedicated for standby operation of volatile memory, and is capable of supplying up to 10 ma loads. The total device features a low quiescent current of 3.0 ma or less when supplying 10 ma from the standby output. This part was designed for harsh automotive environments and is therefore immune to many input supply voltage problems such as reverse battery (12 ), double battery (+24 ), and load dump transients (+60 ). Two Regulated.0 Outputs Main Output Current in Excess of 70 ma On/Off Control of Main Output Standby Output Current in Excess of 10 ma Low Input/Output Differential of Less than 0.6 at 00 ma Short Circuit Current Limiting Internal Thermal Shutdown Low oltage Indicator Output Designed for Automotive Environment Including Reverse Battery Protection Double Battery Protection Load Dump Protection Reverse Transient Protection Economical Lead TO220 Package with Two Optional Leadforms Also Available in Surface Mount D 2 PAK Package LOW DROPOUT DUAL OLTAGE REGULATOR TH SUFFIX CASE 314A 1 SEMICONDUCTOR TECHNICAL DATA 1 T SUFFIX CASE 314B T SUFFIX CASE 314D 1 Device LM293D2T LM293T LM293TH LM293T ORDERING INFORMATION Operating Temperature Range T J = 40 to +12 C Package Surface Mount Plastic Power Horizontal Mount ertical Mount 1 D2T SUFFIX CASE 936A (D 2 PAK) Semiconductor Components Industries, LLC, 2001 April, 2001 Rev. 2 1 Publication Order Number: LM293/D
