applications‚ including uses in programmable output regulation and local on-card regulation. Or‚ by connecting a fixed resistor between the adjust and output terminals‚ the LM317 can function as a precision current regulator. An optional output capacitor can be added to improve transient response. The adjust terminal can be bypassed to achieve very high ripple-rejection ratios‚ which are difficult to achieve with standard three-terminal regulators. LM317 Adjustable

Experiment 13 Charging and Discharging Capacitors 1. Introduction In this experiment you will measure the rates at which capacitors in series with resistors can be charged and discharged. The time constant RC will be found. Charging a capacitor. Consider the series circuit shown in Fig. 1. Let us assume that the capacitor is initially uncharged. When the switch S is open there is of course no current. If the switch is closed at t=0‚ charges begin to flow and an ammeter will be able
