LT1500/LT1501 Low Noise Micropower

Posted on Jun 23, 2012

The LT®1500/LT1501 current mode step-up regulators control both the maximum and minimum inductor current, resulting in continuous inductor current and nearly constant switching frequency and output ripple over a wide load current range. The switching frequency depends mainly on the input and output voltages and the value of the inductor used.

The LT1500/LT1501 have a 0.7A power switch and consume only 200mA of quiescent current. Both parts feature a low-battery detector that remains active in the 8mA shutdown mode. The LT1501 is packaged in an 8-lead SO, and is available in variable, fixed
