The LR12N3-G from Microchip Technology is a high-voltage linear regulator delivering a fixed 88V output. Capable of sourcing up to 50mA, it operates from an input voltage as low as 1.2V. Housed in a compact TO-92 package, it offers excellent ripple rejection of 60dB at 120Hz, ensuring clean power for sensitive applications.
- High-Voltage Output: Provides a stable 88V rail, eliminating the need for multiple lower-voltage regulators in series.
- Low Dropout Operation: Operates with input voltages down to 1.2V, maximizing efficiency and allowing use in low-headroom designs.
- Excellent Ripple Rejection: 60dB PSRR at 120Hz ensures clean, noise-free power for sensitive analog circuits.
- Compact TO-92 Package: Ideal for space-constrained designs requiring high-voltage regulation without a large footprint.
High-Voltage Industrial Sensors
The 88V output capability makes it ideal for powering high-voltage industrial sensors and transducers that require a stable, low-noise supply rail.
Automotive Power Supplies
With a wide input range starting at 1.2V, it can be used in automotive systems where battery voltage fluctuates, providing a regulated 88V for specialized components.
Telecommunications Equipment
Its high output voltage and low current draw suit telecom line driver circuits and biasing networks that need a precise, stable high-voltage reference.
Medical Instrumentation
The low-noise characteristics (60dB PSRR at 120Hz) make it suitable for medical monitoring devices requiring clean, stable high-voltage rails for sensitive analog front-ends.
Battery-Powered Portable Devices
Despite the high output, the low quiescent current (if applicable) and TO-92 package allow for compact, battery-operated devices needing a high-voltage boost for specific functions like biasing MEMS components.
Test and Measurement Equipment
Precision lab equipment can use the LR12N3-G to generate stable high-voltage references for calibration and measurement circuits, ensuring accuracy and repeatability.
