The UM1460S-28 from Union Semiconductor is a versatile 2.8V low dropout linear regulator in a compact SOT-23-5 package. It delivers up to 250mA with an ultra-low quiescent current of 5 µA, making it exceptionally well-suited for battery-powered and power-sensitive applications. The low 0.3V dropout at 150mA ensures efficient operation. The SOT-23-5 package may offer additional functionality such as an enable pin, providing designers with greater control over power management in their systems.
- Design Flexibility: The SOT-23-5 package may include an enable pin for power sequencing and shutdown control.
- Ultra-Low Power: 5 µA quiescent current significantly reduces power consumption in portable devices.
- Stable & Efficient: Low 0.3V dropout at 150mA ensures efficient use of input power.
- Compact Solution: Small footprint ideal for space-constrained PCB designs in modern electronics.
Power Sequencing in Multi-Rail Systems
The SOT-23-5 package often includes an enable pin, allowing designers to implement precise power-up and power-down sequencing for FPGAs or DSPs.
Smartphones & Tablets
Provides a clean 2.8V supply for SIM cards, memory cards, or camera modules, with the enable pin allowing for power gating to save battery.
Portable Test Equipment
The low quiescent current and small package make it suitable for handheld multimeters and calibrators that require long battery life.
RF Transceivers
With 40dB PSRR at 100Hz, it effectively filters low-frequency noise, ensuring stable operation of RF circuits in communication devices.
Battery Management Systems
Can be used to power monitoring ICs in battery packs, with the enable pin allowing the system to shut down the regulator when not in use.
Wearable Health Monitors
The compact SOT-23-5 package and 5 µA quiescent current are ideal for continuous health monitoring devices that need to operate for extended periods.
