The LT3028EDHC#PBF from Analog Devices is a dual-output linear regulator engineered for applications requiring a stable 20V rail. It delivers up to 100mA and 500mA on its two channels, with a low dropout voltage of just 0.45V at full load. Its wide input range down to 1.22V and excellent 65dB ripple rejection at 120Hz make it a versatile solution for industrial, audio, and battery-powered systems. Housed in a compact 16-DFN package, it offers a space-saving power management solution.
- Dual-Output Flexibility: Provides two independent regulated rails (100mA and 500mA) from a single package, reducing board space and BOM cost.
- Low Dropout Operation: With only 0.45V dropout at 100mA, it maximizes efficiency in battery-powered designs by allowing operation close to the output voltage.
- High Ripple Rejection: 65dB PSRR at 120Hz ensures clean, noise-free power for sensitive analog and audio circuits.
- Wide Input Range: Supports input voltages as low as 1.22V, enabling use with low-voltage sources like single-cell batteries.
High-Voltage Sensor Power
With a 20V output and dual 100mA/500mA rails, the LT3028EDHC#PBF is ideal for powering high-voltage analog sensors and precision reference circuits that require a clean, stable supply.
Multi-Rail Industrial Control Systems
The dual-output architecture allows a single device to power both low-current logic (100mA) and higher-current actuators (500mA) in industrial controllers, simplifying power distribution and reducing component count.
Battery-Powered Instrumentation
The low 1.22V minimum input voltage supports operation from a single-cell battery or supercapacitor, making it suitable for portable diagnostic tools and field instruments.
Audio Preamplifier Supply
Its 65dB PSRR at 120Hz effectively filters mains hum, making it an excellent choice for powering audio preamplifier stages where noise rejection is critical.
Automotive ECU Sub-Regulation
In automotive electronics, the LT3028 can post-regulate a noisy 24V bus down to a clean 20V rail for sensitive ECU peripherals, ensuring reliable operation under cranking conditions.
FPGA Auxiliary Rails
The dual outputs can supply separate analog and digital auxiliary voltages for FPGAs, preventing digital switching noise from coupling into analog blocks.
