Key Features
- Fixed 1.8 V output with only 285 mV maximum dropout at 100 mA load
- Wide input voltage range from 2.1 V to 10 V for versatile supply compatibility
- Compact MSOP-8 (MS8) package suited for space-constrained PCB layouts
- Rated for junction temperatures up to 125 °C for industrial environments
Applications
LT3020EMS8-1.8#PBF provides a stable 1.8 V rail in battery-operated handheld devices, IoT sensors, and wearable electronics where input voltage may drop close to the output during discharge. Its ultra-low dropout characteristic makes it well suited for single-cell Li-ion systems where the supply can fall to 2.1 V near end of battery life. The device is also used in post-regulation stages of multi-rail power trees for FPGAs, memory ICs, and RF transceivers requiring a clean, low-noise 1.8 V supply.

Frequently Asked Questions
What is the minimum input voltage the LT3020EMS8-1.8 can accept while still regulating to 1.8 V?
The LT3020EMS8-1.8#PBF requires a minimum input voltage of 2.1 V to maintain regulation of its fixed 1.8 V output. With a maximum dropout of 285 mV at 100 mA load, the device can operate with an input only 285 mV above the output, making it suitable for single-cell battery applications near end-of-life.
Can the LT3020EMS8-1.8 supply enough current for an ESP32 or similar Wi-Fi SoC?
The LT3020EMS8-1.8#PBF delivers up to 100 mA continuously. An ESP32 in active Wi-Fi transmission can peak near 240 mA, which exceeds this LDO's rating. For ESP32 use, a higher-current LDO such as one rated at 300 mA or more is recommended, while LT3020EMS8-1.8 is better suited for low-current peripherals at 1.8 V.
How does the MSOP-8 package size of LT3020EMS8-1.8 benefit compact PCB designs?
The MSOP-8 package measures approximately 3 mm x 3 mm, occupying roughly 9 mm² of board area. This compact footprint allows the LT3020EMS8-1.8#PBF to fit alongside SoCs and RF modules in wearable or IoT designs where board space is limited to a few square centimeters.
Up to what operating junction temperature is the LT3020EMS8-1.8#PBF rated?
The LT3020EMS8-1.8#PBF is rated for a maximum junction temperature of 125 °C, qualifying it for industrial-grade designs. This thermal headroom allows sustained 100 mA operation in enclosures or elevated ambient environments typical of industrial sensor nodes and embedded control boards.
