300mA, low Vin LDO offers higher efficiency in less space

Fairchild Semiconductor offers designers of energy-sensitive systems a 300mA low-dropout (LDO) solution balancing efficiency, transient response, and footprint size. The FAN2564 is a low VIN LDO offering the efficiency of a switcher-based solution but in the footprint of an LDO.

The FAN2564 regulator has a dropout of 100mV and operates from supplies as low as 1.8V, allowing the device to post-regulate from existing low voltage supplies in the system. By operating from a low VIN, the voltage drop across the LDO is reduced, resulting in high efficiency linear power conversion.

Some of the features include:

1. This LDO consumes low quiescent current (45µA at no load) and delivers a fast transient response.
2. Minimal noise
3. FAN2564 uses industry-standard 0402 capacitors that are quite small (1.00mm x 0.50mm), reducing board space in the overall design.
4. Ready to face the space-constrained challenges of applications with a digital load such as portable, medical, computing and computer peripherals,
