LT3014HVEDD#PBF の詳細説明
Product Overview
The LT3014HVEDD#PBF from Analog Devices Inc. is a single-output linear voltage regulator for positive adjustable output rails in surface-mount designs. It accepts input voltages up to 80 V and provides an adjustable output from 1.22 V to 60 V at up to 20 mA. The device uses an 8-WFDFN exposed-pad package, identified as 8-DFN (3x3), and is specified for operation from -40°C to 125°C. An enable control allows the regulator to be placed in a disabled state, while protection functions include over-current, over-temperature, and reverse-polarity protection. With a maximum dropout voltage of 0.57 V at 20 mA and a quiescent current of 20 µA, the regulator supports compact power-management layouts where a low-current positive rail must be generated from a higher-voltage input.
Key Features
- Positive adjustable output with one regulator channel
- Input voltage rating up to 80 V
- Output voltage range from 1.22 V to 60 V
- Output current capability of 20 mA
- Maximum dropout voltage of 0.57 V at 20 mA
- Quiescent current of 20 µA and maximum supply current of 1 mA
- Power-supply rejection ratio of 70 dB at 120 Hz
- Enable control with over-current, over-temperature, and reverse-polarity protection
- Surface-mount 8-WFDFN exposed-pad package, 8-DFN (3x3), for -40°C to 125°C operation
Applications
- Auxiliary positive-rail generation in compact embedded control boards
- Regulated bias supply for low-current analog front-end circuits
- Local voltage regulation in sensor modules powered from higher-voltage buses
- Controlled power domain for battery-powered instrumentation where low quiescent current is required
- Post-regulation of a higher-voltage input to produce a defined positive supply voltage in measurement subsystems
Design & Procurement Notes
When selecting the LT3014HVEDD#PBF, verify that the system input remains within the 80 V maximum rating and that the required output current does not exceed 20 mA. The 1.22 V to 60 V adjustable output and 0.57 V maximum dropout at 20 mA should be used to set input-output headroom during power-tree planning. The enable pin supports rail sequencing or shutdown, but external logic levels must match the chosen input and output configuration. For thermal and PCB layout, account for the surface-mount 8-WFDFN exposed-pad package and the -40°C to 125°C operating range. The 70 dB PSRR specification at 120 Hz is useful when considering rejection of low-frequency input ripple, while the over-current, over-temperature, and reverse-polarity protection features can be coordinated with board-level fault management.
