The LM317LCPW is an adjustable linear regulator from Texas Instruments, offering output from 1.2V to 32V at up to 100mA. With a quiescent current of 2.5mA and PSRR up to 80dB at 120Hz, it provides flexible, clean power in a compact 8-TSSOP package. Ideal for precision adjustable supplies and reference circuits.
- Adjustable Output (1.2V-32V): One part covers multiple voltage rails, reducing inventory.
- High PSRR (80dB @ 120Hz): Excellent ripple rejection for audio and measurement applications.
- Compact TSSOP Package: Saves PCB area compared to TO-220 alternatives.
- Proven LM317 Architecture: Reliable, well-documented design with thermal overload protection.
Adjustable Bench Power Supply
Provides a variable 1.2V-32V output at 100mA for prototyping, with 80dB PSRR ensuring clean test signals.
Precision Reference for ADC
Sets a precise voltage reference (e.g., 2.5V or 5V) for analog-to-digital converters, leveraging low noise and high PSRR.
Battery Charger Control
Regulates charging voltage for small Li-ion or NiMH cells, adjustable to match chemistry requirements.
Audio Equipment Bias
Supplies adjustable bias voltage for op-amp stages, with 65-80dB PSRR reducing hum in audio paths.
Sensor Excitation
Provides a stable excitation voltage for strain gauges or RTDs, adjustable for calibration.
Low-Power Logic Supply
Steps down higher rails to 3.3V or 5V for logic ICs, with TSSOP package saving board space.
