The LP3985IBPX-2.6 from National Semiconductor is a low dropout linear regulator delivering a fixed 2.6V output at up to 150mA. Its exceptionally low 0.1V dropout at full load makes it perfect for battery-powered applications where maximizing usable voltage is critical. With 150 µA quiescent current and 50dB PSRR at 1kHz, it provides clean, efficient power in a compact SOT-23-5 package.
- Ultra-Low Dropout: 0.1V at 150mA enables operation near end-of-battery-life, extending runtime.
- Efficient Power Delivery: 150 µA quiescent current reduces standby losses in portable devices.
- Compact Design: SOT-23-5 package suits space-constrained PCBs.
- Reliable Performance: 50dB PSRR at 1kHz ensures stable output for sensitive loads.
Ultra-Low Dropout Battery Applications
With only 0.1V dropout at 150mA, this LDO can regulate output even when the battery is nearly depleted, significantly extending usable runtime in single-cell Li-ion devices.
Portable Consumer Electronics
Ideal for digital cameras, MP3 players, and handheld gaming consoles where a stable 2.6V rail is needed for logic and memory circuits.
Low-Power Wireless Sensors
The 150 µA quiescent current and low dropout make it suitable for battery-powered sensor nodes that transmit intermittently.
Audio Codec Power Supply
50dB to 40dB PSRR (1kHz-10kHz) provides adequate filtering for audio codecs in portable media players.
Bluetooth Modules
Stable 2.6V output supports Bluetooth SoCs, ensuring reliable communication with minimal voltage sag during transmission bursts.
Wearable Fitness Trackers
Compact SOT-23-5 package and low power consumption fit the tight constraints of wearable devices.
