The AS78L05CZTR-G1 from Diodes Incorporated is a fixed 5V linear regulator in a TO-92 package, delivering up to 100mA. It features a typical dropout of 1.8V and a quiescent current of 5.5 mA. With 62dB PSRR at 120Hz, it effectively rejects input ripple, making it suitable for audio and precision analog applications.
- Proven 78L05 Architecture: Industry-standard pinout and performance, ensuring design compatibility.
- Low Quiescent Current: 5.5 mA helps extend battery life in portable devices.
- High PSRR: 62dB at 120Hz reduces mains hum in audio circuits.
- TO-92 Package: Through-hole package ideal for prototyping and low-cost production.
Microcontroller Power Supplies
5V is a standard logic level for many MCUs. The AS78L05CZTR-G1 provides a clean, regulated 5V from a 9V or 12V input, with 62dB PSRR filtering noise.
Analog Sensor Interfaces
Operational amplifiers and sensors often require a stable 5V rail. The low quiescent current (5.5 mA) makes it suitable for battery-powered data acquisition.
Relay and Solenoid Drivers
Industrial control boards use 5V for logic and driver ICs. The TO-92 package is easy to insert in through-hole designs.
Audio Preamplifiers
5V rails for op-amps in audio mixers benefit from the 62dB PSRR at 120Hz, reducing hum from rectified mains.
Automotive Sensors
With a wide input range, it can regulate vehicle battery voltage (12V) down to 5V for pressure or temperature sensors.
Battery Chargers
Simple charger circuits for NiMH or Li-ion cells often use 5V logic to monitor charge status.
- Q: What is the output voltage?
- A: The fixed output voltage is 5V.
- Q: What is the maximum output current?
- A: The maximum output current is 100mA.
- Q: What is the input voltage range?
