... TEMPERATURE ( C) SHDN (Pin 4): Shutdown Pin. Tie this pin to 0.9V or higher to enable the device. Tie below 0.25V to turn off the device. V (Pin 5): Input Supply Pin. Bypass this pin with a IN capacitor as close to the device as possible. LT1615/LT1615-1 Quiescent Current 1.23V FB NOT SWITCHING ...

... APPLICATIO S I FOR ATIO Choosing an Inductor Several recommended inductors that work well with the LT1615 and LT1615-1 are listed in Table 1, although there are many other manufacturers and devices that can be used. Consult each manufacturer for more detailed infor- mation and for their entire selection of related parts. Many different sizes and shapes are available ...

... LT1615. For higher output voltage applications the 30V MBR0530 can be used. Many different manufacturers make equivalent parts, but make sure that the component is rated to handle at least 0.35A. For LT1615-1 applica- tions, a Philips BAT54 or Central Semiconductor CMDSH-3 works well. Lowering Output Voltage Ripple ...
