1.5V to 5VDC Converter by LT1073

If you want a 1.5V to 5V Step-Up Converter here is a simple circuit using LT1073 from Linear Technology. The LT1073 is a versatile micro-power DC / DC converter. The circuit requires few external components to deliver a fixed output of 5V.

1.5V to 5VDC Converter Circuit by LT1073

LT1073 Pinout

The very low minimum supply voltage of 1V allows the use of the LT1073 in applications Nowhere the primary power source is a single cell. An on-chip auxiliary gain block cans function as a low battery detector or linear post-regulator.The LT1073 is good idea, it Used for dc to dc converter.Average current drain of the LT1073-5 Used as shown in the Typical Application Circuit below is just 135mA unloaded, making it ideal for applications Nowhere Long battery life is Important. The circuit shown cans deliver 5V at 40mA from an input as low as 1.25V and 5V at 10mA from a 1V input.
