As battery voltage rises, current to the battery decreases. When the current is decreased to 150 mA, the charger switches to a lower floating voltage, preventing overcharge. With a discharged battery, the start switch is not needed. However, it is included to allow topping off of even slightly discharged batteries—“Voltage Regulator Handbook.” Reprinted with permission of National is plotted vs. total dose for an HS117 voltage regulator, for biased and unbiased parts, irradiated at two different dose rates. The parts were irradiated with Co60 yrays at dose rates of 61, 0.25 (high temperature), and 0.05 rad/s. These data,.originally reported in 1998, indicate the HS117 circuit exhibits a significant ELDRS effect, but only when no bias is applied during radiation exposure ". This response is consistent with the prevailing model for lowdoserate effects in bipolar parts, The maximum current that can be obtained by using a 7805 regulator is 1A. Assuming VEB (ON) = 0.7V and ft 12 for the transistor, IL = 1 (12 + 1) 12 x — = 11.8A Example 8.3 Referring to Fig. 8.11, assume VEB fon) = 0.7V and ft = 50. Determine the output current 10 and lc for a load of (a)100 £2 , (b) 2 ft in a regulator circuit using 1C 7805. Solution 5V (a) Load Current 1L = = 50mA Voltage across Rj = 50 mA x 7Q = 350m V. Since a minimum of 0.7V is required to switch a transistor from.National Semiconductors are available in the voltage ratings of 5V, 12V and 15V whereas Motorola devices are available in the voltage ratings of 5V, 6V, 8V, 12V, 15V, 18V, 20V and 24V. Different package types along with their lead identification are depicted in Fig. 1.54.

In operation, the LM117L develops and maintains a nominal 1 .25 volt reference (Vref I between its output and adjustment terminals. This reference voltage is converted to a programming current (IpROG) °V R1 (see Figure 13), and this constant current flows through R2 to ground. The regulated output voltage is given by: R2 V0ut = Vref(1+^f) + lAdjR2 Since the current from the adjustment terminal ( I Ad j ) INDEX TO APPLICATIONS CIRCUITS.BASIC REGULATOR CIRCUITS PositiveVoltage Regulators Adjustable Regulator Shunt Regulator Adjustable Series Regulator Series Regulator with Improved Ripple Rejection Adjustable Shunt LM105 93 1 LM105 94 6 LM117 102 1 LM117 102 3 TL430* 128 8 TL430* 128 9 TL432 133 1 TL432 133 2 uA723 147 1 uA723 147 2 uA723 148 12 LM104 89 1 uA723 147 3 LM105 94 5 LM117 102 1 LM117 102 3 LM117 102 5 LM117 102 6 SJ 202971993 Detail specification for types JW117, JW117M and JW117L three terminal adjustable positive voltage regulators of semiconductor integrated circuits Valid SJ 202981993 Detail specification for types JB555 and JB556 precision timers of semiconductor integrated circuits Valid SJ 202991993 Detail specification for type JF147 JFET.input operational amplifier of semiconductor integrated circuits Valid SJ 203001993 Detail specification for types JF155, JF156, JF157, Z.

There are, however, voltage regulators that are adjustable, or programmable, meaning that for a specific voltage in, a specific voltage output can be obtained.
