... This devices can hold 1% accuracy over the full temperature range and load current range, guaranteed, when combined with ratiometrically accurate internal divider resistors and operating with an input/output differential of well under 1V. Advanced Monolithic Systems, Inc. www.advanced-monolithic.com AMS2501/AMS2502 Typical applications for the AMS2501/AMS2502 include 3.3V to 2.5V conversion with a 5V control supply 4.2V conversion with a 12V control supply ...

... The reference voltage is brought out specifically to allow this capability. Advanced Monolithic Systems, Inc. www.advanced-monolithic.com Some of the loads generate large high frequency current transients. The load current step contains higher order frequency components than the output coupling network must handle until the regulator throttles to the load current level ...

... Careful consideration must be given to all sources of thermal resistance from junction to ambient. Advanced Monolithic Systems, Inc. www.advanced-monolithic.com Control section can run up to 125 C, and the Power section can run up to 150 C. Due to the thermal gradients between the power transistor and the control circuitry there is a significant difference in thermal resistance between the Control and Power sections ...
