Key Features
- Fixed 10 V output with ±4% accuracy and 0.1% line regulation ensures precise voltage rails for analog and digital circuits operating from 12.5 V to 30 V input
- Low 2 V dropout voltage reduces power dissipation and heat generation compared to older 78xx-series regulators at equivalent input-output differentials
- TO-252 (DPAK) surface-mount package with exposed pad enables efficient thermal dissipation up to 500 mA continuous output current without an external heatsink
Applications
UA78M10CKVURG3 provides a regulated 10 V supply for industrial control boards, sensor interfaces, and relay driver circuits that operate from unregulated 15 V to 24 V DC rails. Its tight load regulation of 0.2% makes it suitable for powering precision analog signal chains, operational amplifier supply rails, and 10 V reference-voltage systems in data acquisition equipment. The DPAK package integrates easily into compact SMT layouts for automotive accessories, HVAC controllers, and factory automation modules requiring a stable 10 V bias from wide-input DC sources.

Frequently Asked Questions
What is the valid input voltage range for UA78M10CKVURG3 and what input capacitor is recommended?
UA78M10CKVURG3 requires an input voltage between 12.5 V and 30 V to maintain regulation with a nominal 10 V output. A minimum input-to-output differential of 2 V (the dropout voltage) must be maintained at all load currents up to 500 mA. Texas Instruments recommends a 0.33 µF ceramic or 10 µF electrolytic bypass capacitor at the input pin to suppress oscillation and high-frequency input noise.
How does the 0.1% line regulation of UA78M10CKVURG3 benefit analog sensor power supply designs?
With 0.1% line regulation, the output voltage shifts by no more than 10 mV for every 10 V change in input voltage across the 12.5 V to 30 V range. For precision sensors and 10 V-referenced signal conditioning circuits, this means total output variation stays under ±50 mV over the full input range, reducing the need for additional post-regulation filtering. Combined with 0.2% load regulation, the 10 V rail remains stable from no load to 500 mA output.
When is UA78M10CKVURG3 preferred over a switching regulator for generating a 10 V rail from a 24 V industrial bus?
UA78M10CKVURG3 is preferred when load current is below 200 mA and low output noise is critical, as linear regulators produce no switching harmonics. At 100 mA load from a 24 V input, the regulator dissipates 1.4 W, which the DPAK package handles without an external heatsink. For loads above 300 mA where the 14 V input-output differential causes excessive heat (more than 4.2 W), a switching pre-regulator or buck converter is more efficient.
What makes UA78M10CKVURG3 suitable for automotive and industrial environments operating up to 30 V input?
The 30 V maximum input rating accommodates automotive load-dump transients on 12 V vehicle bus and the high-line 24 V DC industrial bus with a safe 6 V headroom margin. The device is specified over a junction temperature range consistent with industrial operation, and its JESD-609 e3 lead-free package complies with RoHS regulations for automotive and industrial applications requiring a minimum 10-year lifecycle at temperatures up to 125 °C.
