Frequently Asked Questions
What load current can the UA78L08ACDRG4 reliably deliver at its 8 V regulated output?
The UA78L08ACDRG4 provides up to 100 mA regulated output current at 8 V with a maximum load regulation of 0.08%, making it suitable for powering low-current microprocessor support circuits and analog sensor bridges in industrial and consumer designs.
How wide an input voltage range can UA78L08ACDRG4 tolerate without damaging the regulator?
The device accepts input voltages from 10.5 V minimum to 30 V maximum, providing a 1.7 V typical dropout voltage. This wide range allows operation from a 12 V automotive rail or a 24 V industrial supply, as long as the input stays below the 30 V absolute maximum rating.
When is UA78L08ACDRG4 preferable to a switching regulator for generating an 8 V rail?
UA78L08ACDRG4 is preferred in noise-sensitive analog front ends where switching noise from a buck converter would degrade ADC accuracy; its linear topology achieves line regulation of 0.175% and output noise below 200 µV RMS, eliminating the need for post-filter inductors.
