What are the key features of LTC3025IDC-1#TRMPBF?
- 85 mV typical dropout voltage at 500 mA output allows regulation from near-flat lithium-ion cells down to 2.5 V input with minimal headroom loss
- 500 mA continuous output current in a tiny 6-pin DFN package enables high-current LDO regulation in board areas under 4 mm²
- 0.08% maximum load regulation and 0.005%/V line regulation deliver stable voltage rails for noise-sensitive ADC and RF circuits
- Micropower quiescent current extends battery runtime in always-on IoT sensor nodes and portable medical devices
- Adjustable output voltage via external resistor divider supports diverse rail requirements from a single LDO part number
What is LTC3025IDC-1#TRMPBF used for?
The LTC3025IDC-1#TRMPBF supplies stable low-dropout regulated power to RF transceivers, precision ADCs, and MEMS sensors in portable IoT devices where the input supply is a single lithium-ion cell discharging from 4.2 V to 3.0 V and the output must remain regulated at 3.0 V or lower. Its 85 mV typical dropout voltage maximizes usable battery capacity compared with conventional 300 mV dropout LDOs, extending device runtime by up to 10% in compact wearables. The 6-pin DFN package and micropower quiescent current also make it suitable for always-on power rails in energy-harvesting sensor nodes and RFID readers where standby current budget is limited to microamperes.

Frequently Asked Questions
What is the dropout voltage of LTC3025IDC-1#TRMPBF at 500 mA, and how does this extend Li-ion battery life?
The LTC3025IDC-1#TRMPBF has a typical dropout voltage of only 85 mV and a maximum of 170 mV at 500 mA output. A lithium-ion cell discharged to 3.0 V can still maintain a 2.9 V regulated output because only 100 mV of headroom is required. Compared with a standard 300 mV dropout LDO, this saves approximately 200 mV of usable cell capacity, extending battery life by 5% to 15% in portable devices drawing 200 mA to 500 mA continuous current.
How accurate is the LTC3025IDC-1#TRMPBF output regulation when the load current changes from 0 mA to 500 mA?
The LTC3025IDC-1#TRMPBF specifies a maximum load regulation of 0.08% across the full 0 mA to 500 mA load range, meaning the output voltage shifts by less than 0.8 mV per volt of nominal output when load current swings from no load to full load. This tight regulation keeps ADC reference voltages and RF power amplifier supplies within 1 mV of their set point, preserving signal-chain accuracy without post-LDO filtering capacitors.
Can the LTC3025IDC-1#TRMPBF output voltage be adjusted, and what external components are required?
Yes, the LTC3025IDC-1#TRMPBF is an adjustable LDO that sets its output voltage with an external resistor divider between the output, the ADJ pin, and ground. Selecting two resistors from the standard E96 series allows any output voltage within the device's operating range to be programmed. A 4.7 µF ceramic output capacitor and a 1 µF ceramic input capacitor complete the application circuit, making the total component count 4 parts for a fully regulated supply.
For a multi-rail IoT board, how much PCB area does LTC3025IDC-1#TRMPBF occupy in its DFN package, and can several regulators share a small zone?
The LTC3025IDC-1#TRMPBF is housed in a 6-pin DFN package measuring approximately 2 mm × 2 mm with 0.5 mm pitch. Each LDO instance occupies roughly 4 mm² of land pattern area, so three independent voltage regulators for 1.8 V, 2.5 V, and 3.0 V rails can fit within a 12 mm² power management zone on a compact IoT node or wearable PCB, which is practical alongside MEMS sensors and BLE SoC components with similar footprint constraints.
