Introduction to LT1070 three-terminal monolithic linear voltage regulator, which has high efficiency and small size, and gives detailed design guide.
The document serves as a comprehensive guide for designing circuits using the LT1070 five-terminal switching regulator. It addresses the challenges of switching regulator design by offering practical tutorials and direct operating considerations intended to make the device easy to use even for those less experienced in this area.
The note covers various aspects of implementation, including smaller versions like the LT1071 and LT1072 with different current ratings, protection strategies for magnetics under overload conditions, frequency compensation, external component selection (inductors, transformers, capacitors), and troubleshooting hints.
| Peak Switch Current (LT1070) | 5A |
|---|---|
| Switch On Resistance (LT1070) | 0.2Ω |
| Ve Pin to Switch Current Voltage | 8ANV |
The LT1071 and LT1072 are identical to the LT1070 except for switch current ratings.
The peak switch current rating for the LT1071 is 2.5A.
The current limit drops at higher temperatures, improving from greater than -0.3%/°C to under -0.1%/°C.
