Product Details
These micropower, low-dropout, low-cost devices are ideal for high-volume, cost-sensitive 3V and 5V battery- operated systems with wide variations in supply voltage that require very low power dissipation. Additionally, these devices are internally compensated and do not require an external compensation capacitor, saving valuable board area in space-critical applications.
