`
`Microchip has introduced the TC1lJ1T_ high-accuracy (typically 10.5%} CM-OS
`upgrade for bipolar low dropout regulators (LDC). The TC1[l17 is offered in a
`SC-TD package, which represents a 50% reduced footprint vs.
`the popular
`SOT-23 package.
`
`The TCiEl17 offers better overall performance than competing devices: better
`Ioadfline transient response, higher output voltage accuracy and supports higher
`output current requirements.
`
`Key performance parameters for the T8101? are:

`
`Individual diodes and or a combination of diodes can be enabled by driving IIC-s
`high and low or switching to inputs {Z}. The number of diodes (D) that can be
`controiled depends on the number of Iios (GP) used.
`
`The equation is: D = GP 1;: (GP - 1).

`
`Digital potentiometers or pots have many uses in today‘s embedded systems. In this
`example, we will implement an embedded “voltage follower" using a PlC1~SF8?'3 microcon-
`trotier and a MCP-4‘i01El digital not both from Microchip Technology, Inc. Basically, the
`PlC® microcontroll-er {MCU} will read the analog voltage and instmct the digital pot to
`reproduce the input voltage. Because we are interested in analyzing the analog input and
`output and the smart plug-in interface {SPIN} to the digital pot, the mixed-signal analysis
`capabilities of the Agilent 54642!) mixed signal oscilloscope {MSG} will come in handy.
`
`Designing the Volltage Follower
`
`Figure 1 shows the simplified system used for testing, which consists of a filtered analog
`input to a P|C1fiF8?3. three digital lines connecting the PIC MCU to the ltilCP41U1D pot,
`and the output of the pot. Two analog and three digital lines on the oscilloscope monitor

`The sine-wave screen shown in Figure 3 displays the flexibility of the 546420. Using deep
`memory, a feature that makes the M80 very easy to use, the time base can be expanded to
`read the specific SP] data for each analog section. In addition to SPI triggering, the MSG has
`triggering features for USB, PCT", and CAN Bus. Other common measurements, such as,
`phase delay and frequency, are also easily displayed. Only three digital channels were used
`in this example; by using the 13 additional digtal inputs of the oscilloscope, more data can be
