LRO-2.6∼4.2/1.8∼3.3 for Li-Ion /SoC interface

 

Linear Regulators tend to be embedded for Portable devices commonly using Lithium-Ion batteries as power source with a main challenge: maintaining the best voltage regulation over the longest battery discharge cycle.
With an input range from 2.6 V to 4.2 V, LRO-2.6~4.2/1.8~3.3 provides a nominal output voltage rail programmable from 1.8 V to 3.3 V for extended battery lifetime (near end-of-discharge). Its high Power Supply Rejection Ratio (PSRR) for high stability and low intrinsic noise makes LRO-2.6~4.2/1.8~3.3 3 the optimal solution to supply SoC analog parts with a stable and quiet voltage.

 

Key benefits

To maximize the operation time of your battery:

  • To make the supplied islet work with a battery voltage as low as 2.6 V
  • To maintain regulation of the output voltage in low dropout situation.

Low noise operation to supply analog circuitry:

  • High Power Supply Rejection Ratio: 80 dB
  • High capability to filter line transients like GSM burst noises at 217 Hz (TDMA noise).
  • Low intrinsic noise

Low Bill-of-Material:

  • Optimized in density for the best trade-off for the given output current and input voltage range
  • Compatible with both Tantalum and ceramic capacitors
  • A Cost efficient solution compared to external Power Management.

Applications

  • Mobile phone
  • Portable media players
  • all kind of portable devices working on Li-Ion & Li-Poly batteries and other lithium-based batteries
