What are the key features of LT3020EDD#PBF?
- Ultra-low 285 mV maximum dropout voltage at 100 mA enabling operation from near-depleted lithium-ion cells
- 100 mA output current over -40°C to 125°C operating temperature range for industrial and automotive applications
- 8-pin DFN package with exposed thermal pad providing low thermal resistance in a 3 mm x 3 mm footprint
- Single-function LDO topology minimizing quiescent current for always-on supply rails in portable battery devices
What is LT3020EDD#PBF used for?
The LT3020EDD#PBF is ideal for powering low-voltage microcontroller and sensor supply rails in portable medical devices, IoT nodes, and handheld instruments where the battery voltage closely approaches the regulated output voltage. Its 285 mV dropout allows continued operation even when a lithium-ion cell discharges below 3.3 V, extending usable battery run time. Industrial sensor transmitters operating over the -40°C to 125°C temperature range also benefit from this LDO's stable regulation across harsh thermal environments.

Frequently Asked Questions
What is the dropout voltage of LT3020EDD#PBF and how does it affect battery-powered system design?
LT3020EDD#PBF has a maximum dropout voltage of 285 mV at 100 mA output current, meaning it can maintain regulation when the input supply is only 285 mV above the output. For a 3.3 V output rail powered by a lithium-ion battery, the regulator stays in regulation until the cell voltage drops to approximately 3.585 V, extending usable battery life compared to a standard 500 mV dropout LDO by 15 to 20 minutes per charge cycle.
What operating temperature range does LT3020EDD#PBF support for industrial sensor applications?
LT3020EDD#PBF is rated for junction temperatures from -40°C to 125°C, covering the full industrial temperature range specified by IEC 60068-2. This makes it suitable for outdoor sensor transmitters, automotive interior modules, and factory floor measurement instruments that experience both cold winter startup at -40°C and high ambient temperatures near heat-generating equipment exceeding 85°C ambient.
How does the 8-pin DFN package of LT3020EDD#PBF benefit compact PCB power rail designs?
The 8-pin DFN package occupies a 3 mm x 3 mm PCB footprint with an exposed thermal pad on the bottom, enabling low junction-to-board thermal resistance typically below 40°C/W. This compact thermal footprint allows the 100 mA LDO to dissipate up to 500 mW within a small power section, making it suitable for densely populated boards in wearable devices and miniature IoT sensor nodes.
When is LT3020EDD#PBF a better choice than a switching buck converter for a 100 mA supply rail?
LT3020EDD#PBF is preferable to a buck converter when the input-to-output voltage difference is less than 500 mV, eliminating the switching efficiency advantage of a converter and avoiding the EMI generated by 1 MHz to 2 MHz switching. For a 3.6 V input to 3.3 V output supply providing 100 mA, the LDO dissipates only 30 mW while avoiding inductor, diode, and filter capacitor BOM, saving 4 to 5 components and 20 mm² of PCB area.
