Linear Voltage Regulators
{"Image DocumentName": "Linear Voltage Regulators", "Image ImageDescription": "Efficiency: \u03b7 ~ Vout/Vin. e.g 3.6 V supply and 1.8 V operating voltage ~ 50% Iin = Iout. Power is lost as heat (Pdiss = (Vout \u2013 Vout)\u2219Iout) Advantage. Good Power Supply Ripple Rejection (PSRR) Few external components. Inexpensive. Small in size. Quite (no switching) The major advantage of an LDO IC is its relatively quiet operation because it does not involve switching. In contrast, a dc/dc converter typically operates between 50 kHz and 1 MHz, which can produce EMI that affects analog or RF circuits. Advantages: Few external components. Inexpensive. Small in size. Quiet (no switching) Disadvantages: Inefficient. Power is lost as heat.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
