s s s s s s s s s DESCRIPTIO Operates at Supply Voltages From 2.0V to 30V Consumes Only 110µA Supply Current Works in Step-Up or Step-Down Mode Only Three External Components Required Low Battery Detector Comparator On-Chip User-Adjustable Current Limit Internal 1A Power Switch Fixed or Adjustable Output Voltage Versions Space Saving 8-Pin MiniDIP or SO8 Package Supply voltage ranges from 2.0V to 12V in step-up mode and to 30V in step-down mode. The LT1173 consumes just 110µA supply current at standby, making it ideal for applications where low quiescent current is important. The device can deliver 5V at 80mA from a 3V input in step-up mode or 5V at 200mA from a 12V input in step-down mode. Switch current limit can be programmed with a single resistor. An auxiliary gain block can be configured as a low battery detector, linear post regulator, under voltage lockout circuit or error amplifier. For input sources of less than 2V, use the LT1073.
