What are the key features of UA78L10ACD?
- Fixed 10 V output at 100 mA with ±5% accuracy and 0.175% maximum line regulation for stable analog biasing
- Wide 12.5 V to 30 V input range with 30 V absolute maximum rating tolerating transient spikes in industrial supply rails
- 8-pin SOIC (R-PDSO-G8) package with RoHS e4 lead-free construction simplifying PCB assembly in green manufacturing environments
What is UA78L10ACD used for?
UA78L10ACD is used as a fixed 10 V reference supply for op-amp bias networks, analog signal conditioning circuits, and legacy industrial control boards that require a regulated 10 V rail from an unregulated 12 V to 24 V bus. Its wide input tolerance up to 30 V absolute maximum makes it suitable for automotive accessory modules and 24 V industrial bus systems where transient overvoltages are common. The 100 mA output current is sufficient to power small relay coils, indicator LED strings, and analog sensor front ends without an external pass transistor.

Frequently Asked Questions
What is the dropout voltage of UA78L10ACD, and what minimum input voltage is needed to maintain a 10 V output?
UA78L10ACD has a nominal dropout voltage of 1.7 V. To maintain a regulated 10 V output, the input must stay at or above 11.7 V under load. Texas Instruments specifies a minimum input voltage of 12.5 V in the data sheet to ensure the 1.7 V headroom is met across the full 100 mA output current and -40°C to 125°C temperature range.
What output current does UA78L10ACD provide, and which loads can it drive without an external transistor?
UA78L10ACD delivers up to 100 mA of output current at a regulated 10 V output. This 100 mA rating is sufficient to directly drive small signal relay coils (typically 20 mA to 50 mA), LED indicator strings of 4 to 6 series LEDs, op-amp bias networks, and low-power analog sensor circuits without requiring an external pass transistor to boost current.
How does UA78L10ACD's line regulation compare to competitors, and why does this matter for analog signal accuracy?
UA78L10ACD achieves a maximum line regulation of 0.175%, meaning a 10 V output shifts by no more than 17.5 mV across the full 12.5 V to 30 V input swing. For 12-bit ADC reference networks requiring better than 1 LSB stability (approximately 2.4 mV at 10 V full-scale), the 0.175% line regulation is typically sufficient without additional filtering, simplifying the reference circuit design.
