The ET5A5ADJZB from ETEK MICROELECTRONICS is a high-current, low dropout linear regulator delivering a fixed 3V output. It supports up to 1.5A with an ultra-low dropout of 0.18V, making it highly efficient for battery-powered applications. The quiescent current is only 100 µA, and the device offers excellent PSRR of 70dB at 1kHz. Packaged in a tiny 6-WLCSP (1.18x0.77), it is designed for space-constrained, high-performance electronics.
- High Current Capacity: 1.5A output supports demanding loads like processors and flash modules.
- Ultra-Low Dropout: 0.18V dropout at 1.5A minimizes power loss and heat generation.
- Exceptional Noise Rejection: 70dB PSRR at 1kHz provides clean power for sensitive analog circuits.
- Minimal Footprint: 6-WLCSP package is one of the smallest available, ideal for miniaturized designs.
High-Current Portable Devices
With 1.5A output capability, it can power high-current loads like camera flash modules or motor drivers in smartphones.
Battery-Powered IoT Hubs
The low 0.18V dropout allows efficient use of battery voltage down to 3.18V, maximizing usable capacity.
Compact Wearable Electronics
The tiny 6-WLCSP package (1.18x0.77mm) is ideal for smartwatches and earbuds where space is at a premium.
Noise-Sensitive RF Front-Ends
High PSRR of 70dB at 1kHz ensures clean power for RF amplifiers, reducing interference and improving signal quality.
FPGA Core Supply
Provides stable 3V at 1.5A for low-voltage FPGA cores, with low dropout to maintain regulation during load transients.
USB-Powered Peripherals
Regulates 5V USB input down to 3V for peripherals, with low quiescent current for always-on devices.
