Detailed Description for LT3045EDD#PBF
Product Overview
LT3045EDD#PBF from Analog Devices Inc. is a single-output, positive, adjustable linear voltage regulator for surface-mount power management. It supports a maximum input voltage of 20 V and an adjustable output from 0 V to 15 V at up to 500 mA, with a maximum dropout voltage of 0.45 V at 500 mA. The device provides enable, power good, and soft-start controls, plus over-current, over-temperature, reverse-polarity, and under-voltage lockout protection. Its quiescent current is 20 µA, and it is offered in a 10-WFDFN exposed-pad package, also identified as 10-DFN (3x3), with a junction temperature range of -40°C to 125°C.
Key Features
- Single positive adjustable output: 1 regulator, 0 V to 15 V output range, 500 mA maximum output current.
- Input and dropout: 20 V maximum input voltage; 0.45 V maximum dropout voltage at 500 mA.
- Low quiescent current: 20 µA quiescent current; 25 mA maximum supply current.
- PSRR: 117 dB at 120 Hz to 53 dB at 10 MHz.
- Control features: enable, power good, and soft start.
- Protection features: over current, over temperature, reverse polarity, and under voltage lockout (UVLO).
- Package: 10-WFDFN exposed pad (10-DFN 3x3), surface mount; -40°C to 125°C junction temperature.
Applications
- Analog sensor and measurement modules using a positive adjustable rail and PSRR characteristics.
- Embedded logic or mixed-signal boards requiring enable control and power-good status.
- Controlled startup subsystems that benefit from soft start and protection features.
- Battery-powered or portable electronics where 20 µA quiescent current and 500 mA output are relevant.
Design & Procurement Notes
Design planning should account for the 20 V maximum input, 0 V to 15 V adjustable output, and 0.45 V dropout at 500 mA. The 20 µA quiescent current and 25 mA maximum supply current affect power budgets, and PSRR varies from 117 dB at 120 Hz to 53 dB at 10 MHz. Enable, power good, and soft start support controlled power-up and status monitoring. The over-current, over-temperature, reverse-polarity, and UVLO protections address fault conditions, and the operating temperature is expressed as junction temperature from -40°C to 125°C, so thermal conditions require verification. Confirm the 10-WFDFN exposed-pad surface-mount footprint, also identified as 10-DFN (3x3), during layout and procurement.
