The LP2950CZ-5.0G from onsemi is a fixed 5.0V LDO voltage regulator designed for low-power and battery-operated applications. It delivers up to 100mA of current with a low dropout voltage of 0.45V and an ultra-low quiescent current of 120 µA. Housed in a compact TO-92 package, it provides a simple and efficient solution for generating a stable 5V rail from a higher input source.
- Ultra-Low Quiescent Current: The 120 µA quiescent current significantly extends battery life in portable and always-on applications.
- Low Dropout Voltage: The 0.45V dropout allows operation from batteries with a small headroom, maximizing usable battery capacity.
- Simple Fixed Output: The fixed 5.0V output requires no external resistors, simplifying design and reducing component count.
- Compact TO-92 Package: The small, through-hole package is easy to integrate into space-constrained designs and is suitable for prototyping.
Battery-Powered Microcontroller Systems
The LP2950CZ-5.0G's low 120 µA quiescent current and 100mA output make it ideal for powering 5V microcontrollers in battery-operated devices like remote sensors and handheld tools, maximizing operational lifespan.
Portable Instrumentation
Its low dropout voltage of 0.45V allows operation from a 5.5V or 6V battery even as it discharges, ensuring a stable 5V rail for precision analog-to-digital converters and measurement circuits.
Low-Power Logic and Interface Circuits
This regulator provides a clean, stable 5V supply for TTL logic, RS-232 transceivers, and other interface ICs, reducing noise and ensuring reliable communication in industrial control panels.
Memory Backup Supplies
The very low quiescent current makes it suitable for maintaining power to SRAM or real-time clocks in backup scenarios, drawing minimal current from a backup battery.
Consumer Electronics
In devices like remote controls, calculators, and small appliances, the LP2950CZ-5.0G offers a simple, cost-effective solution to derive a stable 5V rail from a 9V battery or a 6V power adapter.
