Microchip Technology’s family of micropower low dropout regulators (LDOs) utilizes low-voltage CMOS process technology. These LDOs provide ripple rejection and dropout characteristics similar to those of their bipolar equivalents, but are significantly more efficient. Also, Microchip’s LDOs can be placed in a shutdown mode, further enhancing their effectiveness in low-power applications. This low-power operation makes Microchip’s family of LDOs ideal for upgrading the LP2980 and MIC5205 bipolar LDOs in cellular phones, pagers, PDAs, laptops, hand-held meters, and other portable applications.
