The ETEK ET63133YB is a fixed 3.3V LDO linear regulator with an ultra-low 900 nA quiescent current. Capable of delivering 150mA, it features a low 0.26V dropout at full load. The 4-DFN (1x1mm) package is ideal for compact, battery-operated devices. Its stable output and low power consumption make it a reliable choice for always-on applications.
- Ultra-Low Power: 900 nA quiescent current extends battery life in standby and active modes.
- High Efficiency at Light Load: Maintains low ground current across load range.
- Small Size: 4-DFN (1x1mm) enables miniaturized product designs.
- Low Dropout: 0.26V at 150mA supports operation near battery end-of-life.
Wireless Sensor Networks
The 3.3V rail is standard for many RF transceivers. The 900nA Iq ensures long sleep-mode life in mesh nodes.
Portable Audio Players
Low dropout (0.26V) allows operation from a 3.6V Li-ion cell down to 3.56V, maximizing playback time.
Smart Meters
Stable 3.3V for metering ICs and communication modules, with low self-consumption for utility compliance.
Medical Implantables
Tiny DFN package and low Iq suit implantable sensors requiring minimal power draw and small size.
Handheld GPS Units
Powers GPS receiver and display logic from a single Li-ion cell, with dropout margin for low-battery conditions.
Remote Keyless Entry
Ultra-low Iq extends coin-cell life in car key fobs, maintaining 3.3V for microcontroller and RF burst.
