Product Overview
Texas Instruments LM78L05ACM is a fixed positive linear voltage regulator in an 8-SOIC surface-mount package. It accepts input voltages up to 30V and delivers a stable, regulated 5V output at up to 100mA. The ACM designation indicates a commercial temperature range of 0°C to 125°C. It includes output transistor safe area protection and is designed for on-card regulation where board space is limited and current demand is low.
Key Features
- Output voltage: Fixed 5V DC
- Output current: 100mA maximum
- Input voltage: Up to 30V (minimum ~6.7V for regulation)
- Output voltage tolerance: ±5% over the operating temperature range
- Temperature range: 0°C to 125°C (ACM commercial grade)
- Package: 8-SOIC surface mount
- Output transistor safe area protection
Applications
- On-card regulation for logic and instrumentation circuits
- Secondary 5V rail for sensors and low-current logic in embedded systems
- HiFi audio and battery-powered sensor circuits requiring a clean, stable 5V supply
- Replacement for Zener-diode/resistor regulation in space-constrained designs
Frequently Asked Questions
Is this the same as the standard LM7805?
No. The "L" in LM78L05 designates the low-power variant, rated at 100mA maximum output current. The standard LM7805 is rated at 1A. Using this part to supply more than 100mA will trigger thermal shutdown.
What is the minimum input voltage required?
The input must be at least approximately 1.7V to 2.0V above the 5V output — roughly 6.7V minimum — for the regulator to maintain a stable output.
Will this fit a through-hole board?
No. This is an 8-SOIC surface-mount package. Through-hole designs require the TO-92 package variant (LM78L05ACZ). A SOP-8 to DIP adapter can be used if surface-mount soldering is not available.
What is the difference between the ACM and AIM versions?
The ACM operates from 0°C to 125°C (commercial range). The AIM covers -40°C to +125°C for industrial temperature environments. This listing is the ACM version.
Verify minimum input voltage and current requirements against your circuit design before installation. The 100mA output limit is a hard constraint in this package.
