Linear Low Dropout Regulator LDO
Microchip's linear low dropout LDO regulators feature ultra-low quiescent current, ultra-low dropout voltage, ultra-high ripple rejection, very accurate output, fast transient response, wide selection of packages and wide input voltage range.charts, graphs and parametric data.
Switching Regulators
Our comprehensive portfolio supports buck, boost, buck-boost and SEPIC designs from 100mA peak output current up to 12A as well as multi-output regulators to support multiple point of load applications such as microprocessors, FPGAs and ASICs.
For higher current applications, please see our selection of Analog and Hybrid PWM Controllers.

| Design Considerations | Linear | Switching |
| Function | Only steps down (buck) so input voltage must be greater than output voltage | Step up (boost), step down (buck), inverts |
| Efficiency | Low to medium, but actual battery life depends on load current and battery voltage over time. Efficiency is high if difference between input and output voltages is small | High, except at very low load currents (μA), where switch-mode quiescent current (IQ) is usually higher |
| Waste heat | High, if average load and/or input to output voltage difference are high | Low, as components usually run cool for power levels below 10 W |
| Complexity | Low, usually requiring only the regulator and low-value bypass capacitors | Medium to high, usually requiring inductor, diode, and filter caps in addition to the IC; for high-power circuits, external FETs are needed |
| Size | Small to medium in portable designs, but may be larger if heatsinking is needed | Larger than linear at low power, but smaller at power levels for which linear requires a heat sink |
| Total cost | Low | Medium to high, largely due to external components |
| Ripple/Noise | Low; no ripple, low noise, better noise rejection | Medium to high, due to ripple at switching rate |

DDR Termination Regulators
DDR Termination Regulators are an essential component to regulating power through DDR transmission lines. Microchip products provide reduced power dissipation and higher efficiency.
Charge Pumps
Charge pump ICs that convert and regulate voltage using capacitive energy storage elements. Charge pumps are efficient and easy to use for applications with low current requirements.
