The AS78L05ZTR-G1 from Diodes Incorporated is a fixed 5V linear regulator delivering up to 100mA. It features a typical dropout voltage of 1.8V at full load and a quiescent current of 5.5mA. The TO-92 package is ideal for through-hole assembly and prototyping. With 62dB PSRR at 120Hz, it provides clean, stable power for low-current digital and analog applications.
- Simple Through-Hole Design: TO-92 package is easy to solder and breadboard, ideal for DIY and educational projects.
- Stable 5V Output: Fixed 5V rail with 62dB ripple rejection at 120Hz ensures reliable logic operation.
- Cost-Effective Solution: Low-cost linear regulation for 100mA loads without switching noise.
- Widely Available: Standard pinout and specifications make it a drop-in replacement for many 78L05 variants.
General-Purpose 5V Logic Supply
With a 100mA output and 5V fixed voltage, this regulator is perfect for powering TTL logic ICs, small microcontrollers, and digital peripherals in hobbyist and educational projects.
Bias Supply for Op-Amps
The 62dB PSRR at 120Hz ensures clean DC bias for operational amplifiers in audio preamps and instrumentation circuits, reducing hum and ripple.
Replacing Zener Diode Regulators
Offering better line and load regulation than simple Zener-based solutions, the AS78L05Z provides a stable 5V rail for small analog circuits.
Low-Power Sensor Modules
Ideal for powering temperature sensors, Hall-effect sensors, and light sensors that require a regulated 5V supply in industrial or consumer applications.
Standalone Voltage Reference
When precision is not critical, this regulator can serve as a 5V reference for comparators and ADC circuits in cost-sensitive designs.
Through-Hole Prototyping
The TO-92 package is breadboard-friendly, making it an excellent choice for prototyping power supplies on perfboards or solderless breadboards.
