The LP38690DTX-5.0/NOPB from Texas Instruments is a fixed 5V low dropout linear regulator capable of delivering 1A of output current. Its low 55 µA quiescent current and 0.8V dropout voltage make it ideal for battery-operated and high-efficiency systems. The TO-252-3 package ensures excellent thermal performance for continuous operation.
- Extended Battery Life: Ultra-low 55 µA quiescent current reduces standby power consumption in portable devices.
- High Current Capacity: 1A output supports power-hungry loads like microcontrollers and wireless modules.
- Low Dropout: 0.8V dropout at full load allows operation from a 5.5V rail with minimal headroom.
- Clean Output: 55dB PSRR at 120Hz suppresses ripple from switching power supplies.
Battery-Powered Industrial Sensors
The low 55 µA quiescent current extends battery life in remote industrial sensors that require a stable 5V rail for analog and digital circuitry.
Automotive Infotainment Systems
With 1A output capability and 0.8V dropout, this regulator powers microcontrollers and display drivers in head units, maintaining 5V even during cranking conditions.
Portable Medical Devices
The 55dB PSRR at 120Hz filters mains-related noise, ensuring clean power for sensitive diagnostic equipment operating from a 5V supply.
Networking Equipment
Provides a regulated 5V bus for small switches and routers, handling transient loads up to 1A without significant voltage droop.
