Bypass with a 4.7uF or greater capacitor.Control pin for output voltage programming. Connect this pin to a resistive divider network between the outputand GND to obtain an output voltage between 2.0V and 5.5V.Active-Low Shutdown Input – A logic low shuts down the device and reduces the supply current to 0.1uA.ConnectSHDNto VCCfor normal operation.Inductor Switching Connection – Internally connected to the drain of an N-channel MOSFET.Output voltage control pin: Connect this pin to the circuit load and cathode of the switching diode.Common terminal for ground reference.Low Battery Detect Comparator Input – Connect to a resistive divider network between the VCCand GND to setthe Low Battery Detect trip point. The LBI threshold is 0.6V.Low Battery Detect Comparator Output – Open drain comparator output. This output is pulled low when VLBIisless than 0.6V. LBO is high impedance during shutdown.SHDNSWVCGNDLBILBOPACKAGEDATAPACKAGEDATACopyright(C)2000Rev. 1.1c, MicrosemiIntegrated Products11861 Western Avenue, Garden Grove, CA. 98-8121, Fax: 714-893-2570Page 2
